I don't like that very much, at last not in the way it's done in sun3
(it should try LABELOFFSET first, otherwise if it happens to have
DISKMAGIC somewhere we could end up reading garbadge before trying the real
label at LABELOFFSET).
Anyway, disklabel isn't cross-endian currently, so this would only work
for big-endian hosts.
