it depends, at least you should use a avr32-linux toolchain. The
avr32-elf one builds u-boot fine but has some runtime flaws. For compile
testing this would be Ok.

Ouch, that is wrong. You got the avr 8-bit variant. There is no mainline
avr32 gcc support!
The patches come from atmel [1] and are for an outdated gcc version
unfortunately.
You cold use the pre-compiled avr32 toolchain provided by kernel.org
[2]. I personally have never run this toolchain but others said it works.
