I'd like to backport the attached patch from master to emacs-25. The idea is that Emacs 25 should work with glibc 2.24 (which is still in draft form). glibc is withdrawing support for some deprecated symbols like malloc_set_state and __malloc_initialize_hook. Emacs is intended to be portable to systems lacking these symbols, but this apparently does not work on ppc64 and ppc64le platforms. As noted in <https://sourceware.org/ml/libc-alpha/2016-07/msg00546.html>, the attached patch has been tested on emacs-25 and works on the affected platforms. I've also tested it on unaffected platforms such as x86 and x86-64.

This issue may be a release blocker for glibc 2.24 (this still hasn't been decided). I'd rather that Emacs didn't get in the way of the malloc performance improvements intended for glibc 2.24, and installing this patch into emacs-25 should help with that.
