There seems to be a bug in handling ppc* arches in koji. Recently there was a scratch build made with --arch-override=ppc64el (a typo, ppc64le was meant by the maintainer), koji took the job and a ppc64 builder picked it up. But koji should fail ASAP with "No matching arches were found" error rather.

could be related to handling of ppc64p7 ...
>>> koji.canonArch('ppc64el') 'ppc64'
Since there have been historically ppc64 variant arches that wanted a ppc64 chroot (e.g. ppc64iseries and ppc64pseries), koji canonicalizes ppc64* to ppc64. We added ppc64le as an exception to that.
