With this patch, vmlinux is not re-built as a result of config_data.gz
change.

It might be a good idea to wrap
x86 default defconfig to set
CONFIG_IKCONFIG=y and run:
make -j50 defconfig tiny.config vmlinux
make -j50 defconfig tiny.config vmlinux
With this patch, vmlinux is not re-built as a result of config_data.gz
change.
