glibc: add patch to fix build on x86
This fixes the following build issues:
In file included from ../sysdeps/x86_64/multiarch/varshift.c:19:0,
from ../sysdeps/i386/i686/multiarch/varshift.c:1:
../sysdeps/x86_64/multiarch/varshift.h: In function '__m128i_shift_right':
../sysdeps/x86_64/multiarch/varshift.h:26:1: error: SSE vector return without SSE enabled changes the ABI [-Werror=psabi]
{
[...]
.../lib/gcc/i686-buildroot-linux-gnu/7.1.0/include/tmmintrin.h:136:1: error: inlining failed in call to always_inline '_mm_shuffle_epi8': target specific option mismatch
The patch has been taken from glibc's patchwork at
https://patchwork.sourceware.org/patch/21003/.
Fixes bug #10156.
