Looking further into this, it appears -mmcu=  is left of AVRLIB_CFLAGS in the 
Makefiles, but is in AVRLIB_ASFLAGS.  When I've added this, my application 
builds happily.

I've also changed AVRLIB_CFLAGS for avr5 to '-Os -mcall-prologues' because 
otherwise it's just too big for my uses.  Isn't multi-libing supposed to build 
variants for speed/size trade offs?
