    Remove needless linking against libstdc++

    This is broken for a number of reasons, including:
    - g++ understands "static-libstdc++ -lstdc++" to mean "link against
      whatever libstdc++ exists, probably shared", which in itself is buggy.
    - another stdlib (libc++ for example) may be in use

    See #11981.
