Yes, you'll end with a -march=3Dnative, but you won't benefit from the "MACHINE_CPU =3D k8 3dnow sse3" or "MACHINE_CPU =3D k8 3dnow" set by bsd.cpu.mk. Note that I don't know exactly where MACHINE_CPU is useful and what it does... I'll maybe check to see if two world binaries end up being exactly the same with your CPUTYPE and with my CPUTYPE+CFLAGS+NO_CPU_CFLAGS.
