KVM's selftests don't play nice with cross-compiles for unsupported architectures.
arm64 and s390 have expilict x86_64 -> {arm64,s390} support from commit 66d69e081b52
("selftests: fix kvm relocatable native/cross builds and installs"), but for
anything else the Makefile assumes an x86_64 target.

Realistically, only test bots are going to run afoul of our laziness.  Do we care
enough to fix this up properly?

Seems easy enough, I will give it a shot.
