+Do not write choice values to .config if the dependency is unmet.

+"# CONFIG_... is not set" should not be written into the .config file
+for symbols with unmet dependency.
+
+This was not working correctly for choice values because choice needs
+a bit different symbol computation.
+
+This checks that no unneeded "# COFIG_... is not set" is contained in
