Hm, interesting...  but I think we might end up in a situation where we
first build the Emacs executable, then update the loaddefs.el, and then
build the Emacs executable again.

But perhaps that's OK -- while we're scanning for new loaddefs every
build, there's seldom any new ;;;###autoloads, so the loaddefs.el file
doesn't update all that often.

I'm not quite sure where the second "make -C" would go, though.
