scl-utils-2.0.2-9.el8.x86_64 contains a garbage in its changelog:

# rpm -q --changelog scl-utils | head
* Tue Jul 02 2019 Pavlina Moravcova Varekova <pmoravco@redhat.com> - 1:2.0.2-9
- use .el8 instead of .el8 (#1725774)
- scl-utils-build own the pkgconfig directory by 
%defattr(-,root,root,-)
%dir %_scl_prefix
%dir %attr(555,root,root) %{_scl_root}
%dir %attr(555,root,root) %{_scl_scripts}
%{_scl_scripts}/enable
%{_root_sysconfdir}/scl/prefixes/%scl
%{_scl_root}/bin

That's caused by an unescaped per-cent character in the spec file:
