The toolchain would like PT_GNU_STACK in our objects for all
architectures to make it explicit whether we are requesting an
executable stack or not.

        * config/aarch64/aarch64-linux.h (TARGET_ASM_FILE_END): define
        to file_end_indicate_exec_stack for .note.GNU-stack emission.

OK, thanks.

Can you back port this to 4.9 and 4.8 ?
