dkS )a\ Red Hat patches ``sys.prefix`` and ``sys.exec_prefix``.
Red Hat's ``00251-change-user-install-location.patch`` changes the install
command's ``prefix`` and ``exec_prefix`` to append ``"/local"``. This is
(fortunately?) done quite unconditionally, so we create a default command
object without any configuration to detect this.

However, MSYS2 incorrectly patches sysconfig ``nt`` scheme. The fix is
likely going to be included in their 3.10 release, so we ignore the warning.
See msys2/MINGW-packages#9319.
MSYS2 MINGW's patch uses lowercase ``"lib"`` instead of the usual uppercase,
and is missing the final ``"site-packages"``.

Debian's ``distutils.sysconfig.get_python_lib()`` implementation returns the
default package path controlled by APT, but does not patch ``sysconfig`` to
do the same. This is similar to the bug worked around in ``get_scheme()``,
but here the default is ``deb_system`` instead of ``unix_local``. Ultimately
we can't do anything about this Debian bug, and this detection allows us to
skip the warning when needed.
