--- Comment #8 from Markus Trippelsdorf <markus at trippelsdorf dot de> ---
But Jakub wrote in the gcc bug:

»As for the ld.bfd optimization that makes linking with ld.bfd work, that is an
optimization if there are any IE relocations then other GD/LD relocations are
turned into them too, because once you have any IE relocations, all of the TLS
has to be static anyway, so the TLS GD/LD calls are just a waste of time.«

So either this is a missed optimization for gold, or ld.bfd generates wrong
code.
