[PATCH 02/35] clockevents: Remove CONFIG_GENERIC_CLOCKEVENTS_BUILD

[Peter Zijlstra]

From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

This option was for simpler migration to the clock events code. Most
architectures have been converted and the option has been
disfunctional as a standalone option for quite some time. Remove it.
