[PATCH] Remove COLLISION_CHECK from Makefile since it's not used.

Subsystem: kernel build + files below scripts/ (unless maintained elsewhere), the rest · Maintainers: Nathan Chancellor, Nicolas Schier, Linus Torvalds

It's rather misleading to have configuration options that don't do
anything.  If someone adds collision checking they might also want to
restore this option.
