[Buildroot] AVR32 patch (& others)

Hi Bernard,
You said that you would commit the prepatory AVR32 patch as soon as
the confusion of multiple sends was sorted out.
Still any problems?

Also:
    No reply on the "BSP" patch, the "TARGET_CFLAGS" and the "local"  patches.
    Are they rejected, or are you guys still thinking about them or ?

Best Regards
Ulf Samuelsson
