kconfig: error out if recursive dependencies are found
Sample: config FOO bool "This is foo" depends on BAR config BAR bool "This is bar" depends on FOO This will result in following error message: error: found recursive dependency: FOO -> BAR -> FOO And will then exit with exit code equal 1 so make will stop.
