My plan is to backport this change to 3.13, 3.14 and 3.15 branches, and then modify the buildbot configuration to add a step running the new pythoninfo-build command.

I made similar changes (with buildbot changes) on:

My plan is to backport this change to 3.13, 3.14 and 3.15 branches, and then modify the buildbot configuration to add a step running the new pythoninfo-build command.

I prepared PR python/buildmaster-config#748 for the buildbot configuration.

Thanks for the review+merge @freakboy3742!

I prepared PR python/buildmaster-config#748 for the buildbot configuration.

The new configuration works as expected: a new "Display build info of the build Python" step has been added.
