Regarding that one specifically, as far as I can see,
HAVE_IRQ_TIME_ACCOUNTING is only relevant for tick-based time
accounting.  If you have CONFIG_VIRT_CPU_ACCOUNTING you get accurate
irq time accounting with or without HAVE_IRQ_TIME_ACCOUNTING.  So how
about making this one:

	irq time acct: HAVE_IRQ_TIME_ACCOUNTING || VIRT_CPU_ACCOUNTING

That would make the "irq time acct" entry for powerpc be "ok".
