commit 0a5768fe9c2e2870269c3a0920f88d9c22d73e33
Author: H.J. Lu <hjl.tools@gmail.com>

    Support x86-64 assmebler without AVX512

    When x86-64 assmebler doesn't support AVX512, we should make
    _dl_runtime_resolve_avx512/_dl_runtime_profile_avx512 as aliases of
    _dl_runtime_resolve_avx/_dl_runtime_profile_avx.  Tested on x86-64
    using GCC 5.2 with binutils 20151008 and GCC 4.8 with binutils 20130219.
    There are no differences in ld.so with binutils 20151008.  There are no
    unexpected failures with binutils 20130219 and 20151008.

        [BZ #19124]
        * sysdeps/x86_64/dl-trampoline.S [!HAVE_AVX512_ASM_SUPPORT]
        (_dl_runtime_resolve_avx512): Make it a hidden alias of
        _dl_runtime_resolve_avx.
        (_dl_runtime_profile_avx512): Make it a hidden alias of
        _dl_runtime_profile_avx.
