Coming back to this, should we stop loading libpthread at all?  That is,
keep libpthread.so.0 around indefinitely (with the placeholder symbols
and symbol versions), and just wait until more and more binaries are
linked with the empty libpthread.a and no longer have a DT_NEEDED
dependency on libpthread.so.0?

Thanks,
Florian
