Discontinue PPC64 as Alternative Architecture

Summary

After a number of projects dropped support for the big endian ppc64 architecture and our move of ppc64 to "maintenance-only" mode few releases back, now a vital dependency, the Eclipse project, stops supporting ppc64. As a consequence we need to discontinue producing any ppc64 content. This is a long time anticipated step as the upstream focus on the little endian variant (ppc64le) on Linux is well known. My email sent to the Fedora PPC mailing list has few more details.
