Yes, this was the problem. I rebuilt world with -march=pentium3 and that did the trick. I'm not sure how CPUTYPE gets handled, but perhaps p4 should expand to -march=pentium3, if possible. There seems no point to generating slower, broken code. Once gcc 3.3 is part of the base system this could be put back.
