I found this mailing list for the MIPS:

This appears to be the TLS requirements based on a link in
one of the messages:

https://www.linux-mips.org/wiki/NPTL

It sounds similar to the others on the face of it but I haven't
read this all in great detail. It references __tls_get_addr()
but the mips doesn't provide one. Where does it come
from so sptls01 links?

What magic is there to provide a functional version?

It seems so close. :(
