Right; moreover, we can't do any better, at least for ELF systems. The
part of the library filename outside of the soname doesn't actually do
anything, as far as I know.

As I understand it, symbol versioning would allow people to successfully
link against consumers of two different major versions of our
libraries. (The OSX two-level namespace would allow the same, I
believe.) That's a win, but I don't really know how it works, and I
didn't think there was a portable way of doing it.
