If you are using Kconfiglib via 'make scriptconfig', the filename of
the base base Kconfig file will be in sys.argv[1]. It's currently
always "Kconfig" in practice.
- The $srctree environment variable is used to look up Kconfig files
- referenced in Kconfig files if set. See the class documentation.

- Note: '(o)source' statements in Kconfig files always work relative to
- $srctree (or the current directory if $srctree is unset), even if
- 'filename' is a path with directories. This allows a subset of
- Kconfig files to be loaded without breaking references to other
- Kconfig files, e.g. by doing Kconfig("./sub/Kconfig"). sub/Kconfig
- might expect to be sourced by ./Kconfig.
