[Distutils] Alternative build system abstraction PEP

[Robert Collins]

Cool. I've replied on the PR as well, but my understanding from Donald
was that from pip's perspective, the spawn interface being the
contract was preferred; the other two differences are I think mostly
cosmetic - except that I'm very worried about the injection
possibilities of the calling code being responsible for preserving
metadata between 'metadata' and 'build-wheel'. That seems like an
unnecessary risk to me.
