Not directly germane but I've been sending patches for this to the x86

The other option is that the clock API stubs itself out when not enabled

These sort of per-arch APIs should be a legacy thing, hopefully we'll
manage to squash them at some point and we should certainly work to
avoid introducing new ones.
