configurations still under development; default is to assume production environment, and reject configs still being worked on. Mark Elf configurations (except sparc and i386) as developmental. Deleted cases matching some generic names in favor of more specific names. (E.g., when we get Alpha support, we'll still only support VMS for Vax.)
