Use depcomp.  Rather than explaining how to do that, it's easier if you
wait until Tom puts the depcomp support code in the tree, then use it
the same way the other stuff will.

A compiler wrapper that helps to do dependency computation as a
side-effect of compilation.  IIRC it first appeared in Automake
(though its authors are also GCC developers, I'm not sure who
initiated it).

Yes.
