Restore i686 on Fedora ELN
    
    No decision to remove i686 support has yet been announced for RHEL 10
    and at this time, dropping that support from GDM is causing cascading
    issues.
    
    If the removal decision gets made, Fedora ELN will disable i686 builds
    on the buildsystem machinery side, not in the specfiles.
