Add support for generating MPW Makefiles. This makes the following changes:

* splitline gets support for changing the continuation character.
* deps returns a data structure for the output routine to format as
  appropriate.
* There's a new program type, [M], for Macintosh.
* There's a new backend to output mac/Makefile.mpw.
