set LDFLAGS="--no-warn-rwx-segments" for build of bl31.elf on iMX8, A64,
H5 and H6 socs. As the link fails with a non-zero exit code (because
of --fatal-warnings).

The ELF linker will now generate a warning message if the stack is made
executable. Similarly it will warn if the output binary contains a
segment with all three of the read, write and execute permission
bits set. These warnings are intended to help developers identify
programs which might be vulnerable to attack via these executable
memory regions. The warnings are enabled by default but can be
disabled via a command line option.
compile error:

aarch64-none-elf-ld.bfd: warning: atf-2.7/build/sun50i_a64/release/bl31/bl31.elf has a LOAD segment with RWX permissions
