I was confused and the race condition patch wasn't actually applied to my tree
on darwin when I did the last set of tests. Current gcc trunk still fails the
profile related test cases on darwin with undefined symbols...

Reverting the race condition patch eliminates this problem. So the question
becomes is whether emulated tls expected to be sufficient for this task? I
tried the inverse of inhibiting the use of -DHAVE_CC_TLS instead and I still
get the same unresoived symbols.
