in` arms. These patterns whitelist canonical CPU types that are
allowed with any vendor. The former arm accepts a provided vendor,
and the latter arm defaults a vendor when none is provided. Split
`case $basic_machine in` in to two, and then pre-default the
missing vendor so that only the explicit-vendor rules are needed.

I got rid of this forcing, as it can hide an error from the user and
is unlike how other OSes are handled. I added fallbacks for clix (MiNT
already had some) such that at least the following stil work:
$ ./config.sub clipper-clix
clipper-intergraph-clix
$ ./config.sub m68k-mint
m68k-atari-mint
$ ./config.sub mint
m68k-atari-mint
"clix" (as opposed to "nonsense-clix", ie. with at least one "-"
before) never worked, so I didn't add a short-hand to make it work
like "mint".

I'm not sure why this was originally added. It's certainly not needed
anymore because the OS will never be duplicated onto the send of the
`basic_machine`. If the user passed `unknown` or no vendor, this will
already be filled in. If they passed something more specific, it's
customary to respect that.

"wrs" is just a vendor that can be handled with all the other vendor
exceptions for two-component cases. `wrs) os=vxworks` can instead be
put with the other OS defaults down below.

Instead of just catching manufacturers as OSes across the board, catch
them just as the second of two components. This prevents nonsense
like:
