I'm even not sure why we need this in 8. As far as I can see it is not
used in the jdk sources.
As far as I know we only use it in the hotspot sources, but for
hotspot we already set it in make/linux/makefiles/ppc64.make

That's because we now have the SA for ppc64 in jdk9. Tiago is
currently working on a downport to jdk8u.
