In /etc/make.conf:
CPUTYPE?=athlon-xp
CFLAGS=-O -pipe
COPTFLAGS=-O -pipe

This gives a generic gcc line like:
cc -c -O -pipe -march=athlon-xp -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes  -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual  -Wundef -fformat-extensions -std=c99 -g -nostdinc -I-  -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000  -mno-align-long-strings -mpreferred-stack-boundary=2  -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -ffreestanding -Werror  /usr/src/sys/cam/cam_xpt.c

Also, since some of the comments have mentioned timing windows, I
should to mention that this is a UP system with PREEMPTION enabled.
