Exports CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC to the kernel .config
based upon menu choices under Global build settings --> Kernel build
options. For simplicity, /proc/config.gz support is assumed, but if
kernel_menuconfig has disabled CONFIG_PROC_FS it will be pruned in
oldconfig.

+ This option enables the complete Linux kernel ".config" file
+ contents to be saved in the kernel. It provides documentation
+ of which kernel options are used in a running kernel or in an
+ on-disk kernel. This information can be extracted from the kernel
+ image file with the script scripts/extract-ikconfig and used as
+ input to rebuild the current kernel or to build another kernel.
+ Unless PROC_FS is disabled, it will also be exported via
+ /proc/config.gz.
