Hi,

the attached patches contain various Python build system improvements
including an original TOML parser (which may be used by other build
systems and importers in the future too) and fixes for #62781 and #63044.
I’m also pushing the patches to the pyproject-toml branch. As always,
a world rebuild is required.

Cheers,
Lars
