This change alone doesn't work, since Free Threading or Debug Build would override build-details.json installed by the regular Release Build. We should decide first if we have a single build-details.json, or one per build. (I suggest discussing that on the issue.)

A single build-details.json is specified in the current PEP. We can always add new ones, but I think the "main" one should stay.

I'll note that Fedora already installs the "regular" optimized build last, precisely to overwrite any common files.

Anyway, this PR fixes an issue you get when installing only the free-threaded build, for example.
The interpreter name that generate-build-details comes up with doesn't match what's in the Makefile.

This change alone doesn't work, since Free Threading or Debug Build would override build-details.json installed by the regular Release Build.

Only debug builds would, free-threading has its own directory, as of GH-121293.

I opened GH-142269 to only include build-details.json in make install, debug builds installed with make altinstall should no longer include it. I think that makes sense.

Thank you for adding the news entry!

No worries! This should have been merged already, but it looks like it was a fluke in the CI. I just restarted it, so hopefully it will merge anytime now 😊

Ah. We should just update the branch to fix this CI illness.
