Ah.  That's probably reasonable.  Still a bit of a PITA for us, as there
are various places that do give a static variable an initializer
pointing to another static.  But that could be worked around I think.
I thought you were saying that the compiler would forbid taking a TLS
variable's address even at runtime.
