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?
