Do you use -march=native -mtune=native with clang in
freebsd-current on all those architectures?

I can build qt5-gui with "-march=i486", "-march=i686"
"-march=i686 -mmmx", "-march=i686 -mmmx -msse".  I'll
be adding each of -msse2, -msse3, -mssse3, -mcx16,
-mfxsr, and -msahf to CFLAGS to see which one is causing
the problem.

If adding all of the -target-feature options turned on
by core2 work with i686, I'll then up i686 and repeat.

In the end, this looks like a "wrong code" issue with
llvm/clang/clang++.
