at one point i wrote a generic board/board.mk that board/*/Makefile could 
inherit.  then all board/*/Makefile would need is to declare COBJS-y.  i'm not 
sure if that's a useful step, or if we just pick a single dir like common and 
make it work by a direct include of the top level Makefile.  once we get those 
issues hashed out, we can move on to others one by one.
