I have the following bit of stuff in my mk.conf file:

----- snip, snip -----
.ifdef BSD_PKG_MK
# pkgsrc only options
.else  # BSD_PKG_MK
COPTS?= -pipe ${DEFCOPTS}
# For cross-compiling
. if ${MACHINE_ARCH} == sparc
COPTS+=-mcpu=v8
. elif ${MACHINE_ARCH} == sparc64
COPTS+=-mcpu=ultrasparc
. elif ${MACHINE_ARCH} == powerpc
COPTS+=-mcpu=750
. elif ${MACHINE_ARCH} == alpha
COPTS+=-mcpu=21164a
. elif ${MACHINE_ARCH} == i386
COPTS+=-march=pentium2 -mcpu=pentium3
. elif (${MACHINE_ARCH} == m68k) && (${MACHINE} == mvme68k)
#COPTS+=-m68040 -msoft-float -save-temps
#COPTS+=-m68040 -msoft-float
COPTS+=-m68040
. endif
.endif  # BSD_PKG_MK
