 Any -march flags?  I hunted down a similar (same[0]?) problem when
 compiling mesa with -mfpmath=sse.  At the end this worked well:

 -O3 -march=i686 -msse -mfpmath=387 -DUSE_X86_ASM -DUSE_MMX_ASM
 -DUSE_3DNOW_ASM -DUSE_SSE_ASM

 [0] z-clipping was way off, either too far behind z_front or too far in
     front of z_back.  The other planes had similar problems.
