I would strenuously object to something like this going upstream. This is an
uncommon scenario, and it would be for specific external memory chips and
unfairly exclude others.
If you want to do this for your copy of AVR GCC then that's your business.
AFAICT, you haven't even explained the details of your system, what chip you
are using, and why you really think you need more memory.
