Yes. It was decided this be a hard error so it gets fixed. The newlib TLS change
broke libdl and it is being fixed for the release. I have done what I can and
know about but some archs need help from those who know about it.

I am not sure about moxie, if it does not have TLS support it can disabled.

The issue I faced was no score interface to get the TLS base for a thread to
determine a symbol's offset. If we had that and something to say if TLS is
supported libdl would be easy to fix.
