See Ulrich Drepper's TLS document. It's a hybrid between ia64 and
sparc64. I think you can use the ia64 datastructures, but I think
the thread-pointer points to the TCB, not the TLS block as for
ia64. How exactly depends on what the compiler emits. Our in-tree
gcc does not emit TLS access sequences, so I wouldn't worry too
much about it.

I think the gcc port has been updated, so we can check if that one
has TLS support on alpha.
