[PATCH] D49397: Pass CMAKE_C_FLAGS to the custom libc++ build too

What about C++ flags? libc++ is a C++ library so those are likely going to be important as well. Rather than lumping both C and C++ flags together into a single variable, we should probably consider adding two new keyword arguments to `add_custom_libcxx`, `CMAKE_C_FLAGS` and `CMAKE_CXX_FLAGS`, and use those to pass C and C++ flags separately to libc++ build.
