 NOTE: Starting with Kconfiglib 10.0.0, the Kconfig filename passed to
 Kconfig.__init__() is looked up relative to $srctree (which is set to '{}')
 instead of relative to the working directory. Previously, $srctree only applied
 to files being source'd within Kconfig files. This change makes running scripts
 out-of-tree work seamlessly, with no special coding required. Sorry for the
 backwards compatibility break!
