This comes from Tom's postinstall invocation using the source tree method
for -s (instead of etc.tgz) and a discrepancy in special case handling
for aarch64:

 - src/etc/Makefile does:

	MAKEDEV_MACHINE=${"${MACHINE_CPU}" == "aarch64":?${MACHINE_CPU}:${MACHINE}}

   and then invokes src/etc/MAKEDEV.awk with MACHINE="aarch64"

 - src/usr.sbin/postinstall/postinstall does no special case handling
   and invokes src/etc/MAKEDEV.awk with MACHINE="evbarm"

There are two (more or less) easy fixes, but main objective is to get rid
of the special case handling:

 - unify arm and aarch64 majors into a single file
 - additionally pass MACHINE_CPU to the awk script and do all special
   handling there (this would require a new command line arg for postinstall(8))
