There still the case when you're building compiler-rt without having libc++ around in which case you need to fallback onto whatever C++ library is available is on host. Using libc++ whenever the source is available and we're building with Clang, independently of other options, would be fine with me.

I was thinking about the right testing strategy. The lit setup already links explicitly against libstdc++, so if we use libc++ whenever possible, the existing tests should be sufficient to check the two libraries work together. We may consider adding additional lit configuration which also uses libc++.
