folks, can i fix this in Makefile.defs by replacing -O9 with -O2?

Makefile.defs tries to test that:
ifeq ($(CC_CLASS), 4.x)
CPU ?= athlon64
CFLAGS+=-minline-all-stringops \
-falign-loops \
-ftree-vectorize \
-mtune=$(CPU)
else
#if gcc 3.0+
ifeq ($(CC_CLASS), 3.x)
CPU ?= athlon
CFLAGS+=-minline-all-stringops \
-falign-loops \
-mcpu=$(CPU)
in my opinion it is better to fix Makefile.defs rather than overwrite
what it is doing.
