Support for including *.mk files

[Timothy Baldwin]

Since having to edit 4 rmk files every time a system independent change is made
is a bit silly, here is a patch to allow the common rules to be split off to
a shared file.  I will submit a patch to do so later.

Also I add ".DELETE_ON_ERROR:" to make make delete targets if there is an
error building them.

        Support including *.mk files.  Fix filename collisions.
        Better cleanup on build errors.

        * genmk.rb: Fixed list rules moved to Makefile.in. Recognise
        appending to variables with "+=".
        (PModule): Use full pathname to generate *.lst filenames.

        * Makefile.in: Fixed list rules moved from genmk.rb.
        (.DELETE_ON_ERROR): New special target.
