Subject: [PATCH] 00251: Change user install location
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Set values of base and platbase in sysconfig from /usr
to /usr/local when RPM build is not detected
to make pip and similar tools install into separate location.

Fedora Change: https://fedoraproject.org/wiki/Changes/Making_sudo_pip_safe
Downstream only.

We've tried to rework in Fedora 36/Python 3.10 to follow https://bugs.python.org/issue43976
but we have identified serious problems with that approach,
see https://bugzilla.redhat.com/2026979 or https://bugzilla.redhat.com/2097183
