A 'make -n' dry-run is used as part of the /compat/vcbuild and
/contrib/buildsystems code. The commit ee9be06 (perl: detect new files
in MakeMaker builds, 2012-07-27) was not aware of that dry-run usage
and thus would not execute the target.
Add a comment to the make file stating the issue and the available
solutions of either NO_PERL or a '+recipe'.
