Fair point. It does go on at length for all the MACHINE_ARCH types, but
doesn't list the plain MACHINE_CPUARCH. In all cases, it is either the one
MACHINE_ARCH supported, or the common prefix of all the MACHINE_ARCH
supported (though when we delete armv5, that will become slightly
inaccurate, so a table is likely good).
