consolidate per-arch stack overflow debugging options

Browse source 
Original posting:

	http://lkml.kernel.org/r/[email protected]

Several architectures have similar stack debugging config options.
They all pretty much do the same thing, some with slightly
differing help text.

This patch changes the architectures to instead enable a Kconfig
boolean, and then use that boolean in the generic Kconfig.debug
to present the actual menu option.  This removes a bunch of
duplication and adds consistency across arches.
