llvm-3.7 @3.7-r229298 fails building on 10.6.8

[udbraumann]

As I was trying to update clang-3.7 from 3.7-r226372_0 to 3.7-r229298_0 I received the following error:

:info:build PrettyStackTrace.cpp:39:8: error: thread-local storage is unsupported for the current target

Anyone able to interpret this message?

r133050 should address this for now.

Thanks for the work-around. I have relaunched building after cleaning, however, shortly after

That is another issue, ​http://llvm.org/bugs/show_bug.cgi?id=22631 llvm.org seems to be down at the moment, but I'll get a fix in sometime soon.
