Tha problem that src/share/mk/bsd.cpu.mk doesn't know how to handle
CPUTYPE=native correctly.

CPUTYPE=core2
i386:
MACHINE_CPU = ssse3 sse3 sse2 sse i686 mmx i586 i486

amd64:
MACHINE_CPU = ssse3 sse3 amd64 sse2 sse mmx

CPUTYPE=native
i386:
MACHINE_CPU = i486

amd64:
MACHINE_CPU = amd64 sse2 sse mmx

See http://www.freebsd.org/cgi/query-pr.cgi?pr=conf/112997 for one possible fix.
