I doubt you have really tried my patch.  DEBUG_FLAGS becomes
part of CFLAGS in bsd.{prog,lib}.mk, and bsd.sys.mk is only
parsed after, so it covers this case too:

# make devfs.o
cc -O -pipe -march=pentiumpro   -Wsystem-headers -Werror -Wall -Wno-format-y2k -
W -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wreturn-type -Wcast-
qual -Wwrite-strings -Wswitch -Wshadow -Wcast-align -Wuninitialized  -c devfs.c
# make DEBUG_FLAGS=-O0 devfs.o
cc -O -pipe -march=pentiumpro  -O0 -Wsystem-headers -Werror -Wall -Wno-format-y2
k -W -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wreturn-type -Wca
st-qual -Wwrite-strings -Wswitch -Wshadow -Wcast-align  -c devfs.c
