While macros can be put in there, avr-gcc doesn't #define the
"atmega644" term, but __AVR_ATmega644__ instead. So this would require
something like

#ifdef __AVR_ATmega644__
#define MCU "atmega644"
#elif ...

All the Makefiles I've seen so far do the reverse, like setting the
--mcpu parameter according to some earlier definition. Then you can use
this earlier definition directly.
