Fix python-flint build failure [full build]

[agriyakhetarpal]

For some reason python-flint failed on main: https://github.com/pyodide/pyodide-recipes/actions/runs/15062463362/job/42340019530

In pyodide/pyodide#5626, we pinned Cython<3.1, but this seems to be resolved as python-flint 0.7.1 (which is being updated to here) is now compatible with Cython 3.1.0a1.

This PR updates the versions of python-flint and FLINT, and updates FLINT's build script for WASM compilation.

So I think there's a bug here in calc_diff.py that didn't come up before—or we could maybe call it a missing feature—as I would have expected that the script would automatically calculate that building python-flint also requires flint, libgmp, and libmpfr to be built, too. I don't think there is a nice way to grab all the dependencies from the recipe file as a list and pass it along to pyodide build-recipes <...>, or is there? Because even if we were to do it and ask it to build flint,libgmp,libmpfr,python-flint, it would have seen that the first three were built already and stored in the repodata, and would proceed to build just python-flint (as intended).

Should we also allow full builds on labels and on commit messages? I didn't look too closely and I noticed that it applies only to the PR title.

FLINT is definitely found, the error from the Meson logs is here:

Okay, so python-flint is building perfectly now: https://github.com/pyodide/pyodide-recipes/actions/runs/15077583734/job/42388339511?pr=91#step:15:371

The tests are still running, so we should be good to merge once they pass, or I'll have more things to do here :)

Okay, the python-flint tests are passing but I don't see why the other failures don't show up in other PRs; these packages are not related to python-flint in any way. I'll debug them later today.

Thanks!

@agriyakhetarpal Those are because of a new Cython version. pyodide/pyodide#5626.

You can run ./tools/sync_packages.sh to apply the changes from the pyodide/pyodide repository. It may remove some changes like #90. So you'll cherry-pick some changes though.

[ryanking13]

I'll go ahead and merge this, so I can fix other cython related issues. Thanks @agriyakhetarpal!

Thanks for the review and for getting to them before I could! :)
