With setuptools changes, it is increasingly hard to build using bdist_rpm or test using setuptools.

The setuptools 69.3.0 started to change dashes to underscores, leading to
+ /usr/lib/rpm/rpmuncompress -x -v /src/build/bdist.linux-x86_64/rpm/SOURCES/python-libssh-0.0.1.tar.gz
error: File /src/build/bdist.linux-x86_64/rpm/SOURCES/python-libssh-0.0.1.tar.gz: No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.deAYuh (%prep)

pypa/setuptools#3593

The setuptools 72.0.2 removed setup.py test command, leading to
/usr/lib/python3.13/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'test_suite'
  warnings.warn(msg)
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
