Bug report
Bug description:
autoconf minimum requirement was bumped to 2.72 through https://github.com/python/cpython/issues/115765
This breaks configure regeneration for CentOS Stream 9/RHEL9 (shipping 2.69 and extra 2.71) and CentOS Stream 10/RHEL10 (shipping 2.71). I presume other distros as well. We currently patch our spec files, lowering the version (to 2.69 and 2.71) makes them work fine.
I (re)discovered the issue by doing some testing on the newly added CentOS Stream buildbot.
And as far as I can see there is nothing used from 2.72, no functional changes. Requiring 2.72 is too aggressive and it seems it was not tested on any major distros at the time.
CPython versions tested on:
CPython main branch, 3.16, 3.15, 3.14
Operating systems tested on:
Linux

Research direction
Review the autoconf minimum-version change introduced by issue 115765 and the configure-regeneration path it affects. Reproduce the build on the CentOS Stream 9/RHEL 9 and CentOS Stream 10/RHEL 10 environments mentioned, then verify that the supported distro versions work without patching the spec files.
