GDB is rebasing to version 16.3, which emits `.gdb_index` sections of version 9. Without DWZ support, the rebase will break gdb-add-index, causing all packages to not be created with the `.gdb_index` section.

This was a problem in Fedora 40, and was solved by this backport back on October 7th: https://src.fedoraproject.org/rpms/dwz/c/7c5218e6cdc4299209f5e125db5fcca95abd0f5e?branch=rawhide

The same needs to be done for RHEL9
