It doesn't have to be cross-architecture to be a cross compiler.

I guess that makes sense.  It should be easier to apply a backend patch to 
two versions than it would be with a large frontend patch.

Anyway, after the new platform is brought up, the original 2.067 still won't 
be able to target it and will therefore no longer be a suitable minimum host 
compiler version. This could be fixed by creating a point release for 2.067 
that includes the new platform support, or by bumping the version 
requirement to the latest release.  If we're talking months, then a point 
release is reasonable.  If 2.067 is years old by then, it's probably best to 
bump the requirement.

I think keeping the same minimum version the same for at least ~1 year 
should be reasonable.
