build: Fix 'make -j' handling.

Browse source 
Some build targets create multiple outputs, which can cause problems
when doing parallel builds. Clean up the build system so that all
subdir invocations come from the top-level Makefile and use $(MAKE).
Also fix the FREEDOOM/FREEDM lumps to really include the version
number by using $(shell ...) syntax.
