FWIW, if you're on a distro with a default GCC toolchain, it's pretty typical to use clang together with libstdc++. E.g. if you use clang on Fedora, you're using libstdc++ by default. You have to explicitly pass -stdlib=libc++ to use libc++ instead. So I wouldn't consider this a particularly unusual build configuration. Of course, it's different on distros with a default Clang toolchain, like macOS, where building with anything but libc++ would be pretty unusual.
