Subject[PATCH 6/7] kconfig: keep config.gz around even if CONFIG_IKCONFIG_PROC is not set
From: Steven Rostedt <srostedt@redhat.com>

If CONFIG_IKCONFIG is set but CONFIG_IKCONFIG_PROC is not, then
gcc will optibize the config.gz out, because nobody uses it.

This patch adds "__used" to the config.gz data to keep it around so that
code like extract-ikconfig can still find it.

[ Impact: allow extract-ikconfig to find config.gz ]
