[PATCH 06/14] kconfig: enable CONFIG_IKCONFIG from streamline_config.pl

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

Ingo Molnar suggested that the streamline_config.pl should enable
CONFIG_IKCONFIG to keep the current config in the kernel.
Then we can use scripts/extract-ikconfig to find the current
modules.

This patch changes streamline_config.pl to check if CONFIG_IKCONFIG
is not set, and if it is not, it enables it to be a module.

[ Impact: make current config options easier to find ]
