Unfortunately, this approach doesn't work: using a regenerated avr32
patch from ASF, the madplay build still fails in exactly the same
manner if the architecture-specific optimisations are disabled for

A simpler approach would be to force the arch-specific optimisations
to be enabled for avr32; would that be an acceptable compromise?
