I am not sure what we want :)
We need to specify the instruction set, and the specific target.
We could deduce the instruction set from the target,
but I think it is good to be able to overwrite the instruction set
in case there can be multiple instruction sets for a target.
I think "native" and "generic" should be specified as instruction set,
in the existing option "machine" or renamed as "instruction_set" or "isa".
Let's imagine the first option is "isa" and the new second option is "platform".
We can have a default "isa" per "platform".
The default "platform" would have a default "isa": native or generic?
What else do we need?
