Subject: [PATCH 3.7-rc1] Fix kconfig failure on old environments.

Commit 95ac9b3b "menuconfig: Assign jump keys per-page instead of globally"
used macros which are available in "@(#)queue.h 8.5 (Berkeley) 8/20/94" but are
not available in "@(#)queue.h 8.3 (Berkeley) 12/13/93", making it impossible to
run one of kconfig targets on old environments.

This patch defines missing macros as needed.
