Most of the secondary Makefiles we have are just a couple variable definitions and then an include of Makefile.rules. This patch removes most of the secondary Makefiles and replaces them with a direct invocation of Makefile.rules in the main Makefile. The specificities of each sub-build are listed right there on the recursive $(MAKE) call. All the variables that matter are being passed automagically by make as they have been passed on the command line. The only things you need to specify are the variables customizating the Makefile.rules logic for each image. This patch also removes most of the clean logic from those Makefiles and from Makefile.rules. The clean rule is not required anymore now that we run the testsuite in a separate build directory that is wiped with each run. The patch leaves a very crude version of clean in Makefile.rules which removes everything inside of $(BUILDDIR). It does this only when the $(BUILDDIR) looks like a sub-directory of our standard testsuite build directory to be extra safe.
