[PATCH] Add Sortix support

[Jonas 'Sortie' Termansen]

Hi,

This patch recognizes Sortix in config.sub and config.guess.

I'll be releasing Sortix 1.0 this December. I've been patching these files
manually in the ports tree and have about fifty patched files. I noticed an
unfortunate trend where projects takes years to upgrade the files, so it's
probably best to upstream my changes now.

Sortix isn't using the vendor field because there is nothing to set it to
and config.sub sets it to a default when software needs it. Since triplets
occasionally end up in installed files, I would prefer for the default
build triplet found by config.guess to match what I usually set --build to.
For that reason, I made config.guess leave out the vendor field for Sortix.

I couldn't find an example of config.guess leaving out the vendor field, so
perhaps the interface requires it to return a fully specified triplet? But
I notice configure scripts run config.sub on the config.guess result, so
that isn't a problem. Perhaps there are other users of config.guess? Feel
free to change it to a default -unknown- if this is a problem.

I decided not to append ${UNAME_RELEASE} in config.guess because I don't
need it and it is extra cruft at the end. uname -r might contain a dash at
point in the future. This isn't done for Linux either, so this is fine.

Jonas
