That would deviate from the GCC interface, so I have chosen for the current situation:
```
$ avr-gcc -mmcu=avr2 -o /dev/null x.c
$ avr-gcc -mcpu=avr2 -o /dev/null x.c
avr-gcc: error: unrecognized command line option '-mcpu=avr2'
$ avr-gcc -march=avr2 -o /dev/null x.c
avr-gcc: error: unrecognized command line option '-march=avr2'
$ avr-gcc -v
...
gcc version 6.3.0 (GCC)
```
