Implementing it this way was easier for two reasons:

1. Pushing the hook out to the dependencies isn't easy in terms of
automake's implementation.  That is, our Perl code is ugly, so our
Makefile code ends up ugly

2. Pushing the hook out means that if the user has a -local as well as
a -hook then we have to rewrite the -local target to add a new
dependency.  We've never rewritten user targets, so this is a
major(-ish) change to contemplate.
