[PATCH] D22469: [compiler-rt] Don't require c++ headers when configuring compiler-rt builds

I don't think that would work for all cross-compilation scenarios.  Using C++ introduces a dependency on libunwind for ARM targets unless we pass in `-fno-exceptions` and `-fno-unwind-tables` to the compilation test.
