I agree the paths in those scripts is incorrect, *but*:

 * Should these scripts have been installed in the first place? I don't
   think there are useful for the typical usage of the Python
   interpreter, so maybe we want to get rid of them.

 * Instead of fixing this patch manually in every Python script
   installed, can we investigate on how to fix the root of the problem?
   I'm the one who has reworked the patches that get Python to
   cross-compile, and I know this stuff is really painful, but I think
   it's worth at least trying to understand a bit if there could be a
   way of handling things. From what I remember the problem is that the
   host-python uses its host sysconfig parameters even when building
   things for the target, simply because the whole Python things has
   absolutely zero understanding of the fact that we could be using
   Python on one machine to build stuff that will run on a different
   machine.

Thoughts?
