gbuild: get rid of processdeps.awk

The only thing that processdeps.awk does that is actually useful is to
be able to set the target name freely, but that is only important for
the default resource file which was just renamed.

Instead hack makedepend to provide the required functionality directly:
- write dummy rules for included files so builds don't break on
  rename/removal
- format deps one per line like concat-deps expects
- concat-deps expects standard POSIX line ends, so open in binary mode
  (also disable that awful backup copying nonsense)

Though in retrospect it would perhaps be a better investment of time to
try to replace makedepend...
