Can you show the options to (if any) and the output of "./configure"?
What's your gcc version?

Or rather, missing support for some of the x86 SIMD intrinsics that we
use. You could probably get around this by installing newer gcc.

Something like this might work to produce a non-SIMD build:
make distclean
./configure --disable-native-tests CFLAGS='-O2 -mno-sse2 -mno-mmx -U__SSE__'
IIRC, the last "-U__SSE__" was needed specifically on Linux with glibc,
where fully disabling compilation of SSE intrinsics didn't work, so you
might instead have better luck with the cleaner "-mno-sse" since you're
on a different system.

If this intrinsic is the only one missing, you could define its
equivalent e.g. using one of the examples from:

But probably more are missing as well.
