I verified this problem using FC4, release 1261.  I don't actually need 8K
myself but the point is that, under make menuconfig, if kernel debugging is
turned off then 8K is the default which leads to an undefined reference to
irq_ctx_init in function init_IRQ.  It may not be reasonable to expect the
kernel to build under all combinations of configs, but it should build for
default configs.
