toolchain: also source the musl package

Browse Source 
We do source the glibc and uClibc packages in the toolchain menu,
because they do provide user-visible options. However, we do not so
far source the musl Config.in file

However, in 822be87 (toolchain: include C libraries in legal-info),
a Config.in file for musl was explicitly created, so that:
  - legal-info would work (needed at the time, probably no longer needed
    nowadays),
  - the appropriate packages are enabled, like netbsd-queue or kernel
    headers.

Yet, we do not source musl/Config.in, which means we do not get
netbsd-queue or kernel-headers to be selected:

    $ make distclean; make menuconfig
        Toolchain  --->
          C library ---> musl
      save-and-exit
    $ grep BR2_PACKAGE_LINUX_HEADERS .config
        [nothing]
    $ grep BR2_PACKAGE_NETBSD_QUEUE .config
        [nothing]

Fix that by sourcing musl/Config.in at the same place we source glibc
and uClibc.

Normally, we do have a check in place that verifies that a package
that is not enabled is not a dependency of another package that is
enabled. However, musl is only a dependency of host-gcc-final, which
is a host package and has no corresponding BR2_PACKAGE_HOST_GCC_FINAL.
Thus host-gcc-final is not in the PACKAGES variable, and thus does not
trigger our check.
