Hmm. We now have a number of ways of achieving this (some of these
only work in some contexts):
Defining CFLAGS with ?= instead of = in /etc/make.conf
COPTS in <bsd.prog.mk>
CWARNFLAGS in <bsd.sys.mk> (included from <bsd.{kmod,lib,prog}.mk>)
DEBUG_FLAGS in <bsd.{lib,prog}.mk>
The latter three obviously don't cover general code, but the plethora
of options is starting to get ugly.
