[PATCH] kbuild: fix CONFIG_EMBEDDED submenu

From: Vegard Nossum
Date: Fri Nov 28 2008 - 12:29:47 EST


Many of the elements of the EMBEDDED submenu were being expanded
in the current menu instead of inside the submenu. This was caused
by the lack of (explicit) dependencies on EMBEDDED. The simplest
fix is to wrap everything (except COMPAT_BRK, which just toggles a
setting) in "if/endif EMBEDDED".
