Fedora downstream patches

• https://src.fedoraproject.org/rpms/python3.10/blob/master/f/python3.10.spec
• https://src.fedoraproject.org/rpms/python3.10/tree/master
• Tracking issue: https://bugzilla.redhat.com/show_bug.cgi?id=1287556

00001-rpath.patch

"Fixup distutils/unixccompiler.py to remove standard library path from rpath"

=> Can be removed, but blocked by a Fedora change.

=> Covered by this Fedora 35 change: https://fedoraproject.org/wiki/Changes/Broken_RPATH_will_fail_rpmbuild

This patch is basically useless, but removing it would require to ensure that no Fedora package use rpath. See: https://pagure.io/packaging-committee/issue/886

See also: https://bugs.python.org/issue36659#msg340731

Added by: https://src.fedoraproject.org/rpms/python/c/f5df1f834310948b32407933e3b8713e1121105b (2010-03-16)

00251-change-user-install-location.patch

"Change user install location to /usr/local if executable is /usr/bin/python* and RPM build is not detected to make pip and distutils install into separate location."

=> Should be proposed upstream as a configure option.

Distutils is deprecated in Python 3.10 and will be removed in Python 3.12. Removing the patch breaks numpy, so the patch is kept for now, we will watch how numpy deals with distutils deprecation/removal.

https://github.com/python/cpython/pull/25718 proposes a long term solution to give Linux distributions a way to customize sysconfig "schemes".

Added by: https://src.fedoraproject.org/rpms/python3/c/332b947dfc8d0f0d3a4525864b121d0f239beb4d (2017-06-26)

00274-fix-arch-names.patch

=> downstream only patch
