* config.sub: Added machines and operating systems for Emacs
ports, since Emacs now uses config.sub for its configuration.
New manufacturers recognized not to be operating systems: High
Level Hardware (highlevel, defaults to using BSD), Gould
(gould, defaults to System V), Commodore (cbm, defaults to
amigados), National Semiconductor (ns, defaults to Genix), and
Masscomp (masscomp, defaults to RTU).
Recognize the NS1600 (ns16k) and the Clipper (clipper) as
processors.
Recognize these processors with default manufacturers: the
Cydra (cydra) from Cydrome (cydrome), the XPS100 (xps100) from
Honeywell (honeywell), and the Orion (orion) and Orion 1/05
(orion105) from High Level Hardware (highlevel).
If the ISC operating system is given with a version number,
don't kill it and set it to 2.2; just have it default to 2.2
if omitted.
Make Irix SGI's default operating system, not SYSV.
Make BSD Encore's default, so it applies for all Encore
machines, not just the umax and mmax abbreviations.
All of Encore's machines use BSD, not just the ns32k-based
ones. Make it the manufacturer's default.
Make it possible to specify an operating system for a Gould
machine. Make sysv the manufacturer's default, so it applies
when we specify the manufacturer as well as when we omit it.
Add Uniplus (uniplus), Iris (iris), Xenix (xenix), and RTU
(rtu) as recognized operating system names.
