AUR package is orphaned

The avr-gcc-atmel AUR package is currently orphaned, so you could adopt it and push your changes there if you are interested in maintaining it.

Not sure if @Virtual-Java has notifications on issues on :)
I'm hoping avr-libc 2.2.0 will provide a lot of the same benefits, if/when it comes out.
Avr on linux does lack a lot of love :)
