I think you'll find everyone else is using mk.conf. Besides by default gcc
produces plain i386 code, if you have a Pentium 3 for example, the following
mk.conf will set gcc to produce much more efficient code:

$ cat mk.i386.conf
_ACCEPTABLE=yes
DEPENDS_TARGET=package

# When doing 'build.sh release' it's safer to use -Os optimisation
# With -O2 and higher, executables may not fit inside ramdisk image, etc
KERNEL_CPUFLAGS=-march=pentium3 -mmmx -msse -mfpmath=sse
KERNEL_CFLAGS=-Os -pipe

PKGSRC_CPUFLAGS=-march=pentium3 -mmmx -msse -mfpmath=sse
PKGSRC_CFLAGS=-O2 -pipe
