Subject: selftests: proc: fix proc-empty-vm build error on non x86_64
Date: Wed, 9 Nov 2022 22:11:03 +0000
The proc-empty-vm test is implemented for x86_64 and fails to build for
other architectures. Rather then emitting a compiler error it would be
preferable to only build the test on supported architectures.
Mark proc-empty-vm as a test for x86_64 and customise the Makefile to
build it only when building for this target architecture.
