For non-POSIX platforms, currently just returns ``sys.platform``.
For MacOS X systems the OS version reflects the minimal version on which
binaries will run (that is, the value of ``MACOSX_DEPLOYMENT_TARGET``
during the build of Python), not the OS version of the current system.
For universal binary builds on MacOS X the architecture value reflects
the univeral binary status instead of the architecture of the current
processor. For 32-bit universal binaries the architecture is ``fat``,
for 4-way universal binaries the architecture is ``universal``.
Examples of returned values on MacOS X:
* ``macosx-10.3-ppc``
* ``macosx-10.3-fat``
* ``macosx-10.5-universal``
.. % XXX isn't this also provided by some other non-distutils module?
