[AD] TLS broken on MinGW?

["Trent Gamblin" <trent@xxxxxxxxxx>]

The attached example should print three address, with bmp1 and target being the same, unless I
messed it up, but I found this out through another program I'm working on... it seems that TLS is
broken on MinGW unless you use DLL TLS. The _tls variable acts like a normal static variable, any
time tls_get is called it returns the same address no matter what thread.
