--- Comment #11 from David Kredba <nheghathivhistha at gmail dot com> ---
I have the same problem with snapshot 4.9-20131222.
Makefile:517: recipe for target 'x86_avx.lo' failed:

-fPIC -DPIC -o .libs/x86_avx.o
I found qt-4.8.5 reporting existence of AVX and SSE 4.2 where I have Core2
only.
So now I am rebuilding my Gentoo system with -O2 -ggdb -pipe -march=native
-mtune=native -mno-sse4.2 -mno-sse4a -mno-avx -mno-3dnow but GCC bootstrap
ignores it and adds -mavx.
