[Distutils] inconsistency between PEP425 and wheel tags

[Brian Wickman]

For now I'm just using bdist_wheel, but the question is more focused on the
dependency resolution side where I need to select from a list of compatible
wheels on a remote server.  As it stands, I will be very unsuccessful if
bdist_wheel produces pp27 tags and my downloader only looks for
distributions tagged with pp22. :-)

Happy to send out some pull requests.  pip, wheel and distlib all get this
wrong.  AFAICT pip/wheel use the same pep425tags code.  Does that have a
shared home?
