I'm adding support for threading LLVM itself, nothing to do with the code that it generates.  For LLVM itself to be thread-safe, we need to have access to certain atomic intrinsics on the target for which LLVM is being built.

I think the current solution handles that, and should work just fine on a cross-compiled system now that I've switched to link-testing rather than run-testing.  Right?
