Since we always want debug.mk whenever we include cc.mk, move the include out of the Makefiles and into cc.mk itself. This also fixes an include order bug in rc/Makefile where debug.mk is included before cc.mk and breaks the default CFLAGS setup in cc.mk. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
