ARCH_DIR was originally added to deal with KVM selftests using the target triple ARCH for directories, e.g. s390x and aarch64; keeping it around just to deal with the one-off alias from x86_64=>x86 is unnecessary and confusing. Note, even when selftests are built from the top-level Makefile, ARCH is scoped to KVM's makefiles, i.e. overriding ARCH won't trip up some other selftests that (somehow) expects x86_64 and can't work with x86.
