The footprint-min test cases intentionally turn CONFIG_PRINTK
off to show the minimal footprint. On ARC, printk() is being used
in some core IRQ management code, resulting in a build error.
On other OSes such as Linux, disabling printk() causes any use
of them to compile to nothing rather than generate a build error.
We should do the same here, we shouldn't try to discourage the use
of console logs in the codebase.
