This reworks a lot of defaults.mk to make some variables more regularly partially overridden on the command line, making e.g. suppression of -Werror easier when warranted. It also makes having per-compiler versions of each thing simpler. The following variables can be overridden, though in some cases only partially: name kind of things in it COMPILER gcc CROSS_COMPILE arm-linux-gnu- CC $(CROSS_COMPILE)$(COMPILER) DEBUGINFO -g OPTIMIZE -O2 -flto WARNINGS -Wfoo -Wno-bar ERRORS -Werror -Wno-error=cpp CPPFLAGS -D and -I CFLAGS $(OPTIMIZE) $(DEBUGINFO) $(WARNINGS) $(ERRORS) LDFLAGS linker options (add-only) CCLDFLAGS -Wl, prefixed linker options (add-only and it's normally machine generated from LDFLAGS HOSTCC $(COMPILER) HOST_CPPFLAGS $(CPPFLAGS) (add-only) HOST_CFLAGS $(CFLAGS) (add-only) HOST_CCLDFLAGS $(CCLDFLAGS) (add-only) This resolves issue rhboot#31 Signed-off-by: Peter Jones <pjones@redhat.com>

-Werror easier when warranted. It also makes having per-compiler

The following variables can be overridden, though in some cases only
partially:
So if you want, say, no -Werror flags, you can simply do:
