Use '--param inline-call-cost=2' the GCC switch.

Without 'inline-call-cost':
$ avr-size main.elf
   text    data     bss     dec     hex filename
   1756     260     134    2150     866 main.elf

With  'inline-call-cost':
$ avr-size main.elf
   text    data     bss     dec     hex filename
   1370     260     134    1764     6e4 main.elf
