I use a shell script to build my multiple AVR target applications.  I make 
different build directories for each target, and then call make with the 
appropriate -mmcu flag.

The point is is that the shell script is easy.  Here, I'll right an example 
right now for you:


arches="atmega16 atmega32"
for arch in $arches ; do
    rm -Rf build-$arch
    mkdir build-$arch
    cd build-$arch
    make MCU_CFLAGS="-mmcu=$arch" -f ../Makefile
    cd ..
done

See, easy.  Sure, you could do it entirely in make, but somehow I don't think 
it would as short, as simple, or as easy to maintain as this.
