To preserve the RHEL 7 ppc/ppc64 multilib environment a few interim c7 gcc/glibc builds will be needed.

I got past the 32-bit glibc issue but I can move back to Fedora 21 easy enough. What’s another 50GB of rpms :) Fedora 19 would be closest to RHEL 7 but doesn’t have ppc64le support. Fedora 20 was the last with ppc (32-bit) and Fedora 21 was the first with ppc64le.
