If they use the recommended script, contrib/gcc_update, they'll get it
right.

If the rule is not to be activated, I'd rather have it in Makefile.in,
even if commented out, than not at all.  How about:

Makefile.in: # Makefile.tpl Makefile.def  # srcdir omitted for clarity
        ...

so, if one removes Makefile.in, we try to rebuild it, otherwise it
won't be modified just because you touched one of the other files, but
the deps are still documented.

Then, when we get --enable-maintainer-mode in the top level, we'll
just have to replace the `#' with @MAINT@.
