I've been using something close to this for years, and then I can leave
COPTS for any other more magical things, such as "-pipe", or the various
other wacky things added there by <bsd.sys.mk>:

---------- mk.conf ----------
# Note DBG and OPTIM must not use ?= and must not be defined at all if
# you want the defaults in <sys.mk> to take effect.
#
.if ${DBG:M*-g*} == ""
DBG =           -g
.endif
#OPTIM =        -O2
---------- mk.conf ----------
