This is nothing to be discussed on avr-libc-dev, as it's simply
a matter of the compiler.  So better use avr-gcc-list instead.

However, make sure you're using a recent compiler version!  GCC 4.7.2
produces:

$ avr-size foo.elf
   text    data     bss     dec     hex filename
    586       0       0     586     24a foo.elf

vs:

$ avr-size foo.elf
   text    data     bss     dec     hex filename
    368       0       0     368     170 foo.elf

(the latter is the 32-bit version)
