[PATCH] powerpc ppc32 fix definition of distribute_irqs

[Andy Whitcroft]

Now that I can attempt to compile powerpc/ppc32 it appears there is 
a problem with the definition of distribute_irqs, this patch
seems to fix it for me.

powerpc: ppc32 fix definition of distribute_irqs

When we select ppc32 under the powerpc architecture we get the
error below.  This relates to defining distribute_irqs when this
configuratiom option is undefined.

      CC      arch/powerpc/sysdev/mpic.o
    .../arch/powerpc/sysdev/mpic.c: In function `mpic_setup_this_cpu':
    .../arch/powerpc/sysdev/mpic.c:788: error: `CONFIG_IRQ_ALL_CPUS'
	undeclared (first use in this function)

Against 2.6.15-rc3.
