Done.

I have discovered that a one-line change to the libproc.h is needed,
and the compiler settings for the little-endian PPC64 in ppc64le.make
can be adjusted:
it can be tuned for Power7, and there is no need for -mminimal-toc.

Will send it the moment my colleague with account at cr.openjdk posts
the webrev.
Thank you for the comments.

I have two additional patches ready for review, one for the jdk/ subrepo
and another for the top-level. What's the procedure there? Can I
reuse the same bug 8036767 for this? Where should I post RFRs?
