Makefile cleanup. This is an attempt to fix and cleanup all of the rules, and get rid of some of the recursion. We still need to invoke make several times when we're building for more than one board, and some things can get a bit weird when that happens, but it should generally work. A single BOARD=foo build should be fully correct, now. I attempted to keep things compatible, so existing Makefiles that include libmc1322x/Makefile.include should still work correctly.

for now you must define BOARD. I'd like it to be though that if board isn't defined then it makes everything.

Put main dir on include path Now the user can supply their own foo.h that obj_foo/board.h will include

Fix a makefile dependency with libraries Using the implicit rules for libraries leads to problems if one of the objects fails to build, but the others are still OK. Just make all library rules explicit to avoid this.

Use a variable for all target objects Instead of specifying them individually. This lets included makefiles (like my audio/Makefile.include) append objects.
