Is this really the right thing to do?
There are some hosts with `-unknown-' that aren't really "unknown" --
"unknown" is just a placeholder since there isn't a better name.

Eg search for `-openbsd' in config.guess.

Could we use some other mechanism, like defaulting to "know nothing"
and then enabling functionality for the platforms we do recognize?
