This happens when you haven't installed avr-libc. Once you have the tools
(binutils, gcc and avr-libc) installed correctly, you should be able to
just make in the demo directory.

You shouldn't need to fiddle with your env vars if the tools are installed
properly. If you want to try to build the demo without installing
avr-libc, you still need binutils and gcc installed and working (required
to build avr-libc anyways), look at the demo rule in Makefile.am file in
doc/api/ for a convoluted example.
