The following changes to the latest rawhide openssl will enable ppc64le and openssl.  I defer to you on implementation (i.e changes) but this should give you a rough guideline of what is needed.

This will include:

1. change to the spec
2. change to opensslconf-new.h
3. additional patch

As we discussed via email, 1.0.2 should have the proper ppc64le upstream enablement.
