  A separate makefile rule was used for split targets which was added
in patch(KVM: arm64: selftests: Split get-reg-list test code). This
could be avoided by minor changes to the recipes of current rule.

I just noticed that with and without this patch we're building the
arch-specific part in tools/testing/selftests/kvm/riscv even when we have
an $(OUTPUT) directory (e.g. O=build). Those build artifacts should be in
build/kselftest/kvm/riscv instead.

Thanks,
