This is a reasonable approach.  Just imagine what a device-specific 
approach would men in the ARM world, not taking into account different 
RAM and flash configurations...

If such linker scripts shall become the default linker scripts then you 
need 200+ emulations to support the 200+ devices.

Maybe you can have a look at how the tools handle different RAM start: 
The compiler just calls the linker with Tdata to provide the 
information.  This you could add a new column to 
./gcc/config/avr/avr-mcus.def and use that information appropriately.
