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. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
