I never indicate that I was going to do anything regarding version
bumps and I still have no plans whatsoever to do so. It probably does
not make sense to do anything until we have a new GCC in the tree.
Just a note to someone who is brave enough to volunteer for the task.

Handling of libpthread/libthr is not anyone's idea of fun, as both
librares are exporting different symbol sets under the same version
name, stick their dirty hands into rtld internals, etc.
