If You plan to make buildworld, use:
CFLAGS=-O2 -pipe -march=athlon-xp
Anyway, if You just use ports collection, and don't make buildworld
CFLAGS=-O3 -pipe -march=athlon-xp
is also reliable, but it might make some trouble when making buildworld.

CFLAGS += ${_CPUCFLAGS}

Earlier in the file you see:
_CPUCFLAGS = -march=${CPUTYPE}

So in effect what is happening:
CFLAGS += -march=athlon-xp

I use the following with no issues on 5.x and CURRENT:
CPUTYPE ?= athlon-xp
CFLAGS = -O2 -fno-strict-aliasing -pipe
COPTFLAGS = -O2 -fno-strict-aliasing -pipe

CPUTYPE doesn't override CFLAGS. Read /usr/share/mk/bsd.cpu.mk. Specifically, the second to last line:

Which CPUTYPE should be used for the AMD Sempron CPU? I'm assuming this is

similiar to an athlon-xp. Perhaps an alias or a new entry should be
created for this CPU?
