[X86] Segfault when building the kernel for i686
Hi,
Rawhide builds of the kernel for x86 have started failing with a segfault:
https://koji.fedoraproject.org/koji/taskinfo?taskID=27618835
+ ./process_configs.sh -n -c kernel 4.18.0

I don't have a setup to try and debug this so I've disabled building on i686 for
now. I know the kernel can be a bit of a PITA to deal with so I'm happy to answer
questions about how things work for whoever wants to take a swing at fixing this.
