Does -CURRENT's gcc generate ___tls_get_addr under any circumstances

I'm working on porting (and getting fully working) lang/mono
version 0.96, and I'm having a problem.  In one of my object
files--mini.lo--I'm getting an extern reference to
___tls_get_addr.  I've been over the source code in mini.c
and all the included headers, and I can't find anything to
get rid of this reference or find a way to resolve it.  As
a result, the linking of the mono runtime binary fails with
this symbol unresolved.

Any and all clues are welcome!
