yes, it has a custom get_build_platform but it doesn't monkey patch
distutils for that/

Sounds like a plan, I'll add this.

FYI

I have the sysconfig module pending for the py3k branch, but I was waiting
a few days to see if everything was OK with the change in 2.x. I guess
I'll merge it after that, then work on the shutil part.

The next big step is the documentation for sysconfig.
