With help from Peter Kjellerstedt <peter.kjellerst...@axis.com> via IRC.
Add a check for pyproject.toml in ${S} and if so check if it has a
[build-system] build-backend. Give the user a helpful warning that
the recipe should be changed to one of the PEP-517 classes (instead of
setuptools3.bbclass).
Add SETUPTOOLS_SKIP_BUILD_BACKEND_CHECK variable to skip this check (and
avoid the warning). This is needed for e.g.
python3-setuptools-rust-native which does not build cleanly with
setuptools_build_meta.bbclass
