That's all x86 assembly, not ARM.

It looks like all that program is doing is trying to select a bundled
software mesa implementation. None of those are probably included in the
Fedora build anyway, I'd suggest patching to not build that executable
at all.

Thanks, I've ripped that all out.

Would someone familiar with arm assembly be willing to take a look?
Unfortunately this is a generated file, but I've attached at copy.

Does arm even implement cpuid?

Thanks.
