--- Comment #14 from H.J. Lu <hjl.tools at gmail dot com> ---
I couldn't tell what the problem is. I have no problem to
configure GCC with
/export/gnu/import/git/gcc/configure --enable-clocale=gnu --with-system-zlib
--with-demangler-in-ld --enable-languages=c,c++ --prefix=/usr/local
--enable-gnu-indirect-function --with-arch=native --with-cpu=native
--with-fpmath=sse
on a non-AVX machine with AVX binutils. x86_avx.cc was compiled with
/export/build/gnu/gcc-native/build-x86_64-linux/./gcc/xg++

There is -mavx in CXXFLAGS. But it won't be used at run-time since my
machine doesn't have AVX.
