	parameter No_Extending, defaulted to False. When No_Extending

	project, get its Id calling Imported_Or_Extended_Project_From
	with No_Extending set to True.
	* prj-strt.adb (Parse_Variable_Reference): If a referenced
	variable is not found in the current project, check if it is
	defined in one of the projects it extends.
