Split libCom/Makefile into individual subdirectories.

The new Makefile fragments in the subdirectories are incomplete and will
not work individually.  Build rules are placed in a separate RULES file.
This approach keeps the instructions for building each file local and
easier to find than in a large Makefile in the parent directory.
