# Recent Python versions support both a libdir (for pure Python modules) and a
# platlib (for $ARCH specific modules). We've always patched Python to use
# the platform directory (such as /usr/lib64/python3.9/site-packages on x86_64)
# for all modules. Perhaps we will rethink this, but since an installed
# setuptools now takes priority for reporting the libdir (and this no longer
# matches the platlib on architectures such as x86_64), let's patch setuptools
# to agree with Python:
