Currently the Makefile.dtc and Makefile.libfdt fragments include a number of things that seemed like they might be useful for other projects embedding the pieces, or for a make dist target. Well, we have no make dist target, it's become fairly unclear that these things would actually be useful to embedders (the kernel certainly doesn't use them), and it's a bunch of stuff with no current users. This patch, therefore, removes a bunch of unused definitions from the Makefile fragments. It also removes a dependency declared in Makefile.libfdt (of libfdt.a on the constituent .o files) which was incorrect (wrong path), and if corrected would be redundant with the similar dependency in the top-level makefile.
