OK, it didn't take me long to come up with "Makefiles suck" ;)

But I did come up with a solution:

ifneq ("$(origin CC)", "environment")
CC = gcc
endif

CC := $(CROSS_COMPILE)$(CC)

This wont let make CC=xx work unless I also add a:

ifneq ("$(origin CC)", "command line")

around the above if, but do we care?
