[U-Boot] Recommended AVR32 toolchain

[Vasili Galka]

Hi Andreas,

I'm trying to verify the correct build of all AVR32 boards. What is
the recommended toolchain to use?

I tried the one that comes with Ubuntu:

sudo apt-get install gcc-avr binutils-avr gdb-avr avr-libc avrdude

But it does not work, I get the following build errors:
