  - nothing provides nim-srpm-macros needed by redhat-rpm-config-178-1.fc34.noarch from copr_xxmitsu_llvm_priority_1]: [DNF reporting that `nim-srpm-macros` is not installable.]

Issue: redhat-rpm-config package depending on non-existing nim-srpm-macros couldn't be installed.
Resolution: redhat-rpm-config is a "core" needed by all RPM builds, therefore either the package needs to stop depending on nim-srpm-macros, or the nim-srpm-macros need to appear in repositories.
