[aur-general] Move community/*avr* to the AUR.

[Thomas Dziedzic]

Hi,

I have noticed that all the avr packages have been orphans ever since I can
remember.

gcc-avr hasn't been updated yet, and wasn't even marked out of date when I
checked today. (had to mark it myself and I don't use it).

I would like to move the following packages to the AUR where someone more
interested in them will be able to take good care of them.

avr-libc
gcc-avr
binutils-avr
avrdude
