    Python distributed by Apple's Command Line Tools has this special scheme
    that's used when:

    * This is a framework build.
    * We are installing into the system prefix.

    This does not account for ``pip install --prefix`` (also means we're not
    installing to the system prefix), which should use ``posix_prefix``, but
    logic here means ``_infer_prefix()`` outputs ``osx_framework_library``. But
    since ``prefix`` is not available for ``sysconfig.get_default_scheme()``,
    which is the stdlib replacement for ``_infer_prefix()``, presumably Apple
    wouldn't be able to magically switch between ``osx_framework_library`` and
    ``posix_prefix``. ``_infer_prefix()`` returning ``osx_framework_library``
    means its behavior is consistent whether we use the stdlib implementation
    or our own, and we deal with this special case in ``get_scheme()`` instead.

    This tries:

    * A special ``osx_framework_library`` for Python distributed by Apple's
      Command Line Tools, when not running in a virtual environment.
    * Implementation + OS, used by PyPy on Windows (``pypy_nt``).
    * Implementation without OS, used by PyPy on POSIX (``pypy``).
    * OS + "prefix", used by CPython on POSIX (``posix_prefix``).
    * Just the OS name, used by CPython on Windows (``nt``).

    If none of the above works, fall back to ``posix_prefix``.
