I'm sorry but that is wrong.

1.) Please do *not* modify "CFLAGS" in "/etc/mk.conf". You will cause
    various build failures.
2.) Please do *not* try to enforce using "-O2". There are packages which
    build without optimization by purpose. It is default under NetBSD for
    all the packages where this optimization level is known to work

The correct setting is:

COPTS=  -march=athlon

Or you could use the "cpuflags" package.

        Kind regards
