Re-write make_makefile.pl, re-work v4l/Makefile
From: Trent Piepho <xyzzy@speakeasy.org>
The make_makefile.pl script is re-written. The old one was nasty. This
one will correctly handle Makefile lines that are continued with a
backslash. It will also generate a dependency list of the Makefile used
to create Makefile.media. This way if any change, Makefile.media will be
automatically re-made by make.
The whole business where make_makefile.pl would call make_kconfig.pl is
removed.
The underlying logic of the main Makefile is completely changed. Make
has a feature where it will make sure any included files are up-to-date,
and then restart itself if any were updated. We now take advantage of
this feature.
Detect when make is building only targets which do not need include files
like .myconfig or Makefile.media, and don't include them in those cases.
