this question is cyclic. and yes, the kernel *have* to be compiled
w/ -O turned on. sorry, I don't remember why.
if you want yo put something to COPTFLAGS, try something like this :
# the only way I've found to see if I'm in the kernel tree or no !
IS_SYS?= ${.CURDIR:M*/sys*}
# make sure COPTFLAGS contains -O for kernel builds.
.if !empty(IS_SYS)
COPTFLAGS= -O
.endif
# add your stuffs...
COPTFLAGS+= -fomit-frame-pointer -fno-builtin
