The calling of that MAKEDEV script (with mounting /dev as mfs before, 
etc.) is done by init(8) itself. See src/init/init.c. It runs "MAKEDEV 
init".

Put (only)  a MAKEDEV into dev/, and NetBSD's init(8) will DTRT.

I've seen other hacks in the past, like creating a dev/ directory 
including entries on your build box, then create a .tar.gz file, put that 
on the disk and extract it early. But I think letting init(8) do the work 
is pretty ok (IIRC g4u uses that too, after trying out several other 
approaches at first :).

Just make sure everything needed by MAKEDEV is there (mknod, chown, chmod, 
chgrp, ...).
