Here is a patch to require binutils 2.24 to build x86-64 glibc.  Tested
with binutils 2.24 and 2.27.  Verified with binutils 2.23 which fails to
configure glibc.  OK for master?

Please put [BZ #20139] at the end of the first line.

The commit message seems to be inconsistent.  Should the “AVX512DQ” on 
the first line actually be “AVX512F”?

Thanks,
Florian

It is not mathvec disabling, it is disabling only some
implementations, they are as wrappers in this case.

From 7b16dd1e64b164f03a457b26eb04071b3e9060b4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Require binutils 2.24 to build x86-64 glibc

If assembler doesn't support AVX512DQ, _dl_runtime_resolve_avx is used
to save the first 8 vector registers, which only saves the lower 256
bits of vector register, for lazy binding.  When it is called on AVX512
platform, the upper 256 bits of ZMM registers are clobbered.  Parameters
passed in ZMM registers will be wrong when the function is called the
first time.  This patch requires binutils 2.24, whose assembler can store
and load ZMM registers, to build x86-64 glibc.  Since mathvec library
needs assembler support for AVX512DQ,  we disable mathvec if assembler
doesn't support AVX512DQ.
