Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process). This keeps the common code clean and lets the arch do whatever crazy crap it wants in its own area. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
