No. I'm referring to in tree archs which do not use the clock events
at all yet. The MIGR symbol allows them to do a step by step
conversion which builds the generic clock events stuff first before
switching over to use them. That's why it was created in the first
place and it has been proven useful when doing such work. So I'd
rather see it stay until all archs actually use the generic framework.

But yes, we can apply your patch and just let them select
GENERIC_CLOCKEVENTS_BUILD instead.
