Add a kludge to fix building shared libs

The .dyn_hi files currently depend on the .dyn_hi files of modules that
they import. But they actually want the .hi files of modules from
another package.This we make the .dyn_hi files depend on the .hi files
so we are sure that they exist and are up-to-date.
