I routinely build all of ARM (32-bit) and AARCH64 (64-bit) targets and
make sure all of them build properly, and concerning CONFIG_USE_IRQ, I
even have a branch set to remove this option since a

	git grep CONFIG_USE_IRQ | grep -vE \
	'(#define|#ifdef|#ifndef|#if.*defined|#undef|#endif)'

shows that it is defined nowhere in our code.

Which source code are you using?

Amicalement,
