Yes.

Yes, that would be the simplest way to achieve this.

I think you could as well hard-code rules for specific targets in the
toplevel Makefile.am.  But then you'd have to keep both the rules in the
toplevel Makefile.am and in the subdirectories in sync somehow.  In a
nonrecursive setup, you'd get that for free.
