Free-threaded Python 3.13 builds

[layday]

It would be helpful to have these prebuilt by e.g. offering a python313 variant such as python313-freethreading. The official Python 3.13 installers offer or will offer free-threaded builds as an option, see https://discuss.python.org/t/pep-703-making-the-global-interpreter-lock-optional-in-cpython-acceptance/37075/37 and there is some discussion on the naming convention in other distros at python/steering-council#221.

I tried python313FreeThreading, while I can disable GIL, I still can't enable JIT because it is not compiled with such

Python 3.13.0rc3 experimental free-threading build (main, Oct  1 2024, 02:03:08) [GCC 13.3.0] on linux

is it out of scope of this issue to ask for a JIT flag in the compilation? I can't open an issue for a feature request, as this is not a new package request, nor a bug report.

You sure can pick what fits best and file a separate issue as this one is closed.
