Sure, symbol versioning would be great to have, but I still don't
know why library versions are bumped when they don't need to be.
It's like we've thrown up our hands and said "Something has changed
in one or more of the libraries, and we don't know how this affects
other libraries, so we're going to bump them all." Speaking for
the thread libraries, they were not users of any of the changed
ABIs -- there was no reason to bump them.
