OK, I'll work on coming up with some patches. Do you have an opinion about
whether it makes sense to make the %_prefix support complete with something
like:

- %python3_sitelib %(RPM_BUILD_ROOT= %{__python3} -Ic "import sysconfig;
print(sysconfig.get_path('purelib'))")
+%python3_sitelib %(RPM_BUILD_ROOT= %{__python3} -Ic "import sysconfig;
print(sysconfig.get_path('purelib', sysconfig.get_default_scheme(),
{'platbase': '%{_prefix}', 'base': '%{_prefix}')})

Without that, the --prefix %{_prefix} additions won't work in isolation,
and will require something else to redefine
python3_sitelib/python3_sitearch.

Thanks!
