I removed the dependency on python-pypa-build for building packages and instead implemented building with a single python invokation. This simplifies bootstrapping Python. The 'install phase also learned how to create scripts in bin/ from an entry points specification. Currently 600 of 2212 packages using python-build-system are failing to build. That’s alot, but most failures so far were related to testsuites, which were not enabled correctly previously because 'check was not replaced manually. And some fail because upstream does not separate sources and tests and a name clash occurs. This also happens when C extensions are build and there does not seem to be a workaround. This number does not include Python 2 packages, which will probably break with this new build system. Since Python 2 is EOL anyway I suggest to entirely remove Python 2 support before merging this changeset. After merging we should upgrade the entire Python ecosystem, because alot of packages are already years old. Cheers, Lars PS: Maxim: This is your ping for a review (via #52269). Thanks :)
