Based on subsequent discussion since I wrote that question, I think
the answer is, "currently, no." Ebuillds would need more metadata, and
portage would need to be more aware of deep dependencies.

I'm not sure of revdep-rebuild's angle, or how it might be able to be
improved to detect errors that don't come from broken linkage.
