Or perhaps do that stuff in swapcontext libc stub? That way someone that
wants to reimplement another thread library on top of our kernel thread
is free to override _UC_TLSBASE being ignored.

But this is another problem beyond the current discussion, which is just
to support _UC_TLSBASE for ports that miss it.
