Okay, that's fair.  I'm only vaguely familiar with the generic _relaxed
variants, but until they land, how do we appropriately declare the
dependency to prevent breaking COMPILE_TEST builds on architectures that
don't have them?  Or should we either bother?

Do we need to introduce a HAVE_RELAXED_IO_ACCESSORS selected by those
architectures with support?
