I wouldn't bother setting CPUTYPE at all. It's more trouble than it's worth.

And you're right: for most ports and for the whole system, it doesn't really
matter. If you have a very specific port that needs particular tuning, it has
either already been tuned individually by the port maintainer, or you could
apply more optimizations yourself (which would likely require a specially
compiled tool chain, when -O<something> with the base gcc/binutils isn't
enough).

Unless you have a very specific need, better leave CPUTYPE alone.
