[gentoo-dev] [PATCH 2/6] distutils-r1.eclass: make esetup.py require setup.{py,cfg}

[Michał Górny]

Make esetup.py fail if neither setup.py nor setup.cfg is available.
To support PEP 517 builds, the function has been modified to work
without setup.py.  However, this also caused esetup.py to implicitly
succeed in installing zero files on non-distutils/setuptools packages.
