Update defconfig files with the following script.

for a in arch/*; do
	arch=$(basename $a)
	for c in $a/configs/*; do
		config=$(basename $c)

	export ARCH=$arch
	make $config && make savedefconfig && mv defconfig $c
	done
done

The defconfig files are long untouched and a
make xy_defconfig; make savedefconfig usually generates quite
a different looking file. Refresh them to make it easier to generate
patches against the configs using
make xy_defconfig; make menuconfig; make savedefconfig

This has been done with the following script.

for a in arch/*; do
	arch=$(basename $a)
	for c in $a/configs/*; do
		config=$(basename $c)

	export ARCH=$arch
	make $config && make savedefconfig && mv defconfig $c
	done
done

* this compile option actually turns on a command, so name it
  accordingly
* also move the Kconfig definition into commands/Kconfig, thus
  placing getopt into the "Shell scripting commands" section
* while at it, improve Kconfig documention
