Hi!

While rebuilding the python related packages against the Python 3.15rc2
version we found that meson-python fails to build from source [1].

The error encountered is: mesonpy.BuildError: The package declares
compatibility with Python limited API but extension module
'extension.abi3-x86_64-linux-gnu.so' is tagged for a specific Python
version.

The issue can be fixed by applying the upstream commit
865aa6138ab5522b3bee540b64d78ca87c4cec2a [2] BUG: adjust regexp to
extract ABI from extension filename

I applied the upstream fix in the sandbox [3] to be able to build the
packages that depend on meson-python, please consider applying the patch
to support the upcoming 3.15 version.

Happy hacking,
