What is needed to let all architectures include Kconfig.preempt?
We should not advertise preemption if not supported,
but we could do this by a simple Kconfig symbol:

config HAVE_PREEMPT
	bool

And let all architectures that supports preemption do:

config "ARCH"
	select HAVE_PREEMPT

But maybe there is a simpler solution
