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.
