This patch is more a workaround to convert such packages as
python-tornado, python-configobj, etc. to PEP517 infrastructure. These
packages just use a build-system section and otherwise rely on the
setup.py file:

[build-system]
requires = ["setuptools"]
build-backend = "setuptools.build_meta"

What is the plan to support this backend? Just use setuptools-rust or
convert "_SETUP_TYPE=setuptools" to PEP517 after the introduction of
Python 12.x?
