We install pydistutils.cfg to catch legacy cases where people
are doing things with easy_install. That code path is not
desirable and increasingly broken, as support for things like
allow-hosts is dropped upstream.
Stop installing the file. This will mean people using easy_install
won't get the benefit of the mirrors, but they shouldn't be
using easy_install anyway.
Remove pydistutils.cfg if it's there
Make sure we don't have any pydistutils.cfg around.
