[issue12246] Support installation when running from an uninstalled Python

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

Paul Moore reported that a Python built in its checkout on Windows has no problem installing, so I’d like to revisit this.  The patch was also incomplete: The install module was changed, but people could still call “pysetup run install_dist”, and that command was not touched.

To support this on Unix too, we have to either fix sysconfig (#6087) or override some sysconfig paths in packaging.

I will shoot an email at python-dev.  There is no pattern for Lib/site-packages in .hgignore, which makes me think that this issue just never showed up before; I think I need approval before I go ahead.
