The idea is to have something purely the same in meaning as 
hw.machine_arch, which does not involve listing foreign ABIs and is also 
why it is "arch" instead of "isa" (since it is "machine_arch"). I'm 
happy to rename it again if there is a clear consensus, though, although 
there is some risk of bikeshedding. I personally have no opinion on what 
it is called so long as it exists.
