DEBUG is a private variable in kernel Makefiles. "config -g MYKERNEL"
is the only correct way to set it. "makeoptions DEBUG=3D-g" is a hackish
way to set it. It depends on knowing the the Makefiles' internals.

It's simpler to have the same global debug option for everything.

No. DEBUG is quite different.

This would break COPTS :-). All places should use something more like:
CFLAGS+=3D=09[-D_KERNEL] ${CWARNFLAGS} ${COPTS} ${DEBUG_FLAGS}
