Perhaps we should work on making propagated-inputs per-output? That way,
:static could propagate the :static output of the dependencies.

This would also be useful in other situations. For example, a package
might contain both a binary and a library, and the library must
propagate its dependencies to make the header files work.

I don't know what a good syntax for this would be.

Thoughts?
