No idea where this "alldefconfig" is coming from (it contains "2.6.36-rc5").
Is this an MMU=y allnoconfig?
It doesn't enable any platforms, which is not supported, and thus it isn't
known how many interrupts are needed.
BTW, I have a local fix to change NR_IRQS to 1 in that case, but that's
far from sufficient to build an MMU=y allnoconfig kernel.
