Well, they aren't *targets*, but *host* and *build* systems.  However, I 
don't think any of them are actually significantly relevant to GCC now as 
host or build systems (and nor do I think we need case statements for 
unsupported host or build systems - just let people try to build and 
possibly have the build fail, a fix for such a failure would better use 
autoconf than special-casing a triplet anyway).
