Crash on Linux_PPC64

I built the source code from github, however the .run installer from the website has errors, so I installed the downloadable binaries updates.

When I try and run ioq3 I get a crash:

ioq3 1.36_GIT_4d82b8b5-2019-08-22 linux-ppc64 Sep 11 2019

I’m not sure if anyone has tested powerpc at all recently, and I would not even expect any of the installers to work under Linux PPC. It’s good that you compiled from source, because we probably will never have modern binaries again for that platform, although a distribution may decide to provide them.

I see that someone else has the exact same issue on GitHub
