to use _sysconfigdata.py to initialize distutils.sysconfig.
But what does this actually do ? I'm sure it is obvious to the python hackers,
but to me,
this short log just describes what the patch does, not what problem it solves
and why this
is a good thing.
Also, doesn't this also apply to python-2.7.x (maybe with some massaging)?
Whatever problem
this is solving surely exists on that code line as well.
