Added comments in calc Makefiles

Browse Source 
Added a bunch of information to the near bottom of HOWTO.INSTALL
    on calc Makefiles.  This information discusses the various
    Makefiles found in the calc source.

    Added comments in various calc Makefiles about their origin.
    In particular, for Makefiles that are constructed such as
    Makefile.simple, custom/Makefile and custom/Makefile.simple
    there are comments about how they were made.

    For all calc Makefiles, including those in sub-directories,
    near the top there is now a line of the form:

	# SRC: ... some message about the origin ...
