Building nx-libs on ppc64le.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57936 could be related, although that also surfaced on ppc64.

In any case, the patch seems not to have been backported to either 4.8.3-9 or 4.8.5-11. Could be worth a stab, but no idea if that's actually fixing the problem.

I've tried backporting the patch mentioned in GCC's BTS, but that didn't change the situation. I guess the ICE is triggered by something else specific to ppc64le.

Also reproducible on 7.4.1708.
