Looks like of all the architecture build failures tracking bugs listed in https://docs.fedoraproject.org/en-US/packaging-guidelines/#_architecture_bui..., the aarch64 one is currently closed:
https://bugzilla.redhat.com/show_bug.cgi?id=922257
Looks like at some point all bugs are indeed closed, but there are now four bugs listed against it. Should the status go back to NEW?
No, we moved everything to ARMTracker and track it all under a single tracker bug, it's more straight forward.
