A few buildroot developer days ago, we said we'd like to get rid of
architecture-specific patching. IIRC avr32 was the only architecture
having such patches. Is it possible to make such patches 'common' in
the sense that they are always named .patch and thus applied for all
architectures?
If the contents should really only be applied to avr32, is it a
possibility to use some #ifdef inside the patch?

Thanks,
Thomas
