[Andreas Rheinhardt]

Andreas Rheinhardt:
> If a target to be built includes a template file, the target's .d file
> includes the template file as a prerequisite; if the code were changed so
> that the template file no longer exists, one would get an error from
> make that it has no rule for the template file target. Therefore add a
> dummy rule for template files to make deleting them possible.
