Hi,

avr-libc has a new repository here: https://github.com/avrdudes/avr-libc

They also have a new release of avr-libc which supports a lot of the newer AVR parts (AVR128D, etc): https://github.com/avrdudes/avr-libc/releases/tag/avr-libc-2_2_1-release

I tested this new release by editing the formula file for [email protected] and it worked fine (I built for the new AVR128DB48 which is only supported in avr-libc 2.2+)

Could we please update this repo to include the latest avr-libc? I am happy to create a PR with the updated URLs/hashes, please let me know.
