I'd say that since the port has options for the older variants, it should
at least be tested that they appear to work at the point the port goes in
(will build libgcc / pass the testsuite for c6x-elf without ICEs or wrong
code being generated) - though it will of course be for anyone in the
community who wishes to use it on those variants to do any performance
tuning for them, or add any missing features for the older variants, and
it would be reasonable to call sorry () in any cases where an option,
language feature etc. isn't currently supported for them.
