Isn't it /usr/share/mk/bsd.cpu.mk's job ?
# make -V CPUTYPE
core2
# make -V MACHINE_CPU
ssse3 sse3 amd64 sse2 sse mmx

I don't know if that's for the base system solely or if it works for
ports too, but at least on this computer I can compile chromium
19.0.1084.52. Maybe you use CPUTYPE?=native, which is unsupported by
bsd.cpu.mk.
