To be clear: I think we should suppress GCC's warnings about
unused static functions regardless of what we do about this
particular problem.  In my experience, such warnings are
almost always false positives for harmless situations,
rather than indicators of an actual bug.

I think this is a very nice solution, and support it.  I'm
probably being stupid, but I'm missing why the static
linking case is hard; why not just provide static
implementations of all the stubbed functions and flat-out
link against them?
