Since this release libc++ splits what was previously the `__config` header into `__config_site` and `__config`, where `__config_site` contains all the defines set at configure time by CMake and gets included by `__config`. Without this patch the include path to `__config_site`s directory is missing in per target builds and therefore including any file of libc++ causes a compilation error.
