Fixes the following security vulnerabilities:
CVE-2019-6488: On x32, the size_t parameter may be passed in the lower
32 bits of a 64-bit register with with non-zero upper 32 bit. When it
happened, accessing the 32-bit size_t value as the full 64-bit register
in the assembly string/memory functions would cause a buffer overflow.
Reported by H.J. Lu.
CVE-2019-7309: x86-64 memcmp used signed Jcc instructions to check
size. For x86-64, memcmp on an object size larger than SSIZE_MAX
has undefined behavior. On x32, the size_t argument may be passed
in the lower 32 bits of the 64-bit RDX register with non-zero upper
32 bits. When it happened with the sign bit of RDX register set,
memcmp gave the wrong result since it treated the size argument as
zero. Reported by H.J. Lu.
CVE-2016-10739: The getaddrinfo function could successfully parse IPv4
addresses with arbitrary trailing characters, potentially leading to data
or command injection issues in applications.
CVE-2019-9169: Attempted case-insensitive regular-expression match

This enables a riscv32 system to be built with a Buildroot generated
toolchain (gcc >= 7.x, binutils >= 2.30, glibc only).
This requires a custom version of glibc 2.26 from the riscv-glibc
repository. Note that there are no tags in this repository, so the
glibc version just consists of the 40 character commit id string.

This update includes two specific fixes that have been backported
to the glibc 2.28 release branch from the glibc master branch:
1) UAPI header file asm/syscalls.h has been merged into the UAPI
asm/unistd.h header file for the RISC-V architecture in the
4.20 kernel. This causes the glibc 2.28 build to break.
2) sysdeps/ieee754/soft-fp: ignore maybe-uninitialized with -O

glibc is not using the autotools-package infrastructure, so we are
calling the ./configure script manually. Currently, the few autoconf
cache variables are passed as arguments to the ./configure script,
while we pass them through the environment in the autotools-package
infrastructure.
So let's pass them in the environment, and use a GLIBC_CONF_ENV
variable to store them. This will allow in a follow-up commit to
conditionally add more autoconf cache variables to the glibc build.

Currently, we do a full git clone of the repository, which takes quite
some time, especially on slow networks.
This was done like that because the initial patch was using the official
repository as the source of the download, and that repository did not
offer remotely-generated tarballs.
But now we've switched to using a mirror on github, which does provide
such a tarball, which provides faster downloads.
Use that.
However, the tarball from github differs from the one we were generating
locally, because the paths inside are different. WE used to create a
archive with paths starting with glibc-glibc-2.26-73-g4b692dfb95[...],
while github does away with the git-describe prefix, and generates paths
that start with just glibc-4b692dffb95[...]. The content are exactly
identicall (checked with a diff), though.
Update the hash accordingly.

glibc upstream has ruled against doing regular point-releases, but they
do have a lot of interesting and important fixes for regressions and
security.
Backporting each patch, or cherry-picking individual patches is off
limits for us, so we just switch to using the currently-latest HEAD of
the maintenance branch instead.
The version number is obtained with:
$ git describe --match 'glibc-*' --abbrev=40 origin/release/2.26/master
The alternative options were:
- download the tarball from the git tree
--> does not work; not an option
- download the 2.26 tarball, and bundle the individual patches in
Buildroot
--> maintenance of patches is a burden; not an option
- download the 2.26 tarball, maintain the list of patches to download from
the git tree
--> not an option for the same reason
So we end up just doing a git clone. The git tree is today about ten
times the size of the tarball, so a rough estimate makes it at about ten
times the download time.
Also upstream doesn't officially provide an https download location [1].
There is one but it's not reliable, sometimes the connection time out and
end-up with a corrupted git repo:
fatal: unable to access 'https://sourceware.org/git/glibc.git/': Failed to connect to sourceware.org port 443: Connection timed out
So switch to using a git mirror from github which is updated once a day [2].
This allow at the same time to clone the git repository faster.
Note: The glibc 2.26 patches are not kept for the arc toolchain since they
are fixing an issue with the new float128 support introduced in x86, x86_64
and powerpc64le.

Finally there's working ARC port of glibc thanks to Vineet and Cuper!
This port is based on pretty recent glibc's master branch and ARC
changes are being reviewed now in glibc's mailing list.
Thus we again have to use sources from our GitHub but as soon as there's
a glibc release with our patches applied we'll switch to upstream releases
and will drop our glibc GitHub repo alltogether.
Note now we cut tags in glibc repo simultaneously with tags
in Binutils and GCC repos and so to make sure everything works in the best
way we plan to update glibc tag together with Binutils and GCC.
Also note as of today ARCompact (AKA ARCv1 ISA) is not supported in glibc
but we plan to fix it soonish so for now we make glibc intentionally
dependent on archs38.
Also note we are not creating directory "2.26" because all patches for glibc
ver 2.26 applies to arc glibc port.

The input to copy_toolchain_lib_root is not one library, not a list of
libraries, but a library name pattern with glob wildcards.
This pattern is then passed to 'find' to get the actual list of libraries
matching the pattern. Reflect this using an appropriate variable name.
Note: if the root of the buildroot tree contains a file matching one of
these library patterns, the copying of libraries from staging to target will
not be correct. It is not impossible to fix that, e.g. using 'set -f', but
maybe it's not worth it.

On some architectures (namely x86-64), glibc may provide a libmvec
library since glibc 2.22, which programs built with gcc OpenMP support
might get linked to.
In order for these programs to work on the target, we need to copy
this library to the target filesystem.
This commit takes care of this for the glibc package (used for the
internal toolchain backend). Note that libraries listed in
GLIBC_LIBS_LIB are silently ignored if they don't exist. Therefore, we
don't need to have any condition on the architecture or glibc version.
For more details on libmvec, see

The eglibc support has been marked deprecated since 2015.08, so it's
time to remove it.

The toolchain-external logic is roughly:
- populate the staging dir by rsyncing the entire ${ARCH_LIB_DIR} and
usr/${ARCH_LIB_DIR} from sysroot.
- populate the target dir by explictly copying some libraries from sysroot
into target/lib and some other libraries in target/usr/lib, the split
being hardcoded into buildroot regardless of the location in the sysroot.
This means that a library libfoo could be located in:
staging/lib/libfoo.so
target/usr/lib/libfoo.so
When debugging an application that links against this library, gdb will
fruitlessly search for 'usr/lib/libfoo.so' in staging, and then suggest to
use 'set solib-search-path' which is a hack, really.
To solve the problem, we need to make sure that libraries from the toolchain
are installed in the same relative location in staging and target.
Achieve this by:
- replacing the convoluted search for libraries using for+find in sysroot
with a simple find in staging.
- determining DESTDIR for each library individually based on the location in
staging.
- treating LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS equivalently
These changes also allow for the removal of most arguments to
copy_toolchain_lib_root in the method itself and their callers.
Test procedure:
- set configuration for a given toolchain
- make clean toolchain
- find output/target | sort > /tmp/out-before
- apply patch
- make clean toolchain
- find output/target | sort > /tmp/out-after
- diff -u /tmp/out-before /tmp/out-after
The only changes should be some libraries moving from lib to usr/lib or vice
versa. Notable examples being libstdc++ and libatomic.

[Thomas:
- use -L instead of -follow in the find invocation, as suggested by
Arnout.
- move the BR2_STATIC_LIBS condition as a make condition rather than
a shell condition, as suggested by Arnout.]

Glibc is currently configured without any "--enable-kernel" option.
This causes it to use the oldest possible kernel API, slowing it down
and preventing it from using any kernel features from later versions.
Since we are likely building a kernel and matching glibc together,
backwards compatability is probably unnecessary so this patch
unconditionally configures glibc with --enable-kernel set to
BR2_TOOLCHAIN_HEADERS_AT_LEAST.

- Add support for mips32r6 and mips64r6 target architecture variants
- Disable unsupported gcc versions
- Disable unsupported binutils versions
- Disable unsupported external toolchains
- Disable unsuported C libraries
- Add a hook in order to make glibc compile for MIPS R6.
[Thomas: slightly tweak the glibc hack explanation, to make it
hopefully clearer.]
