Urgh. Yes, this looks like a real GCC bug; it's not generating any export
directive for the tls var at all. When there's no other export directives
(i.e. without the function) auto-export kicks in, but that behaviour gets
suppressed in the presence of any explicit exports.
Confirmed for both 4.6.0 and 4.3.4. Sigh, I'll go debug GCC and figure out
