subdirmk: Fix bug in regen.mk.in

Apparently, if you just write `;', make knows that the command can't
have done anything.  It therefore concludes tha the target file cannot
have been updated and doesn't bother rereading it.

The result is that you end up using last run's makefiles.

Writing @: fixes this.
