clang-3.3 @3.3-r173279 can't link a C++ program with -fsanitize=thread

[acmorrow (Andrew C. Morrow)]

I'm using clang-3.3 @3.3-r173279 on OS X 10.8.3:

> /opt/local/bin/clang++-mp-3.3 --version
clang version 3.3 (trunk 173279)
Target: x86_64-apple-darwin12.3.0
Thread model: posix

Given a simple program, I'd like to build it with ThreadSanitizer by passing -fsanitize=thread, but the link step fails:

>  cat ./hello_world.cpp
#include <cstdlib>
#include <iostream>

int main(int argc, char* argv[]) {
    std::cout << "Hello, World!\n";
    return EXIT_SUCCESS;
}
>  /opt/local/bin/clang++-mp-3.3 ./hello_world.cpp -fsanitize=thread -o ./hello_world

Here is a -### dump of the link line:

Ideally, clang-3.3 would support ThreadSanitizer out of the box.
