[PATCH] Make IKCONFIG an embedded option, enabled by default

From: Alexander Holler
Date: Wed Jul 25 2012 - 00:14:37 EST


Knowing (being sure) which configuration was used to build a (maybe running)
kernel is important for many scenarios.

It's usually much more important than saving a few kb in the size of
the kernel. Therefor turn on CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC
by default and make them visible only when CONFIG_EMBEDDED is enabled,
preventing premature optimization.
