[PATCH] D31617: [CMake][libcxx] Use builtins rather than gcc_s when compiler-rt is requested

[Petr Hosek via Phabricator via llvm-commits]

I'd prefer not having to manually specify which runtime to use as well, but it seems like there're still some unresolved issues in https://reviews.llvm.org/D25568. This change is just a fix to ensure that the existing logic works in all cases. If https://reviews.llvm.org/D25568 gets approved and lands I'd be fine if it replaces the this logic.
