	* prj-part.ads, prj-part.adb (Parse): Add Target_Name parameter. Pass
	Target_Name to Get_Path call.
	(Parse_Single_Project): Likewise.
	(Post_Parse_Context_Clause): Likewise.
	* prj-env.ads, prj-env.adb (Find_Project): Add Target_Name parameter.
	Call Initialise_Project_Path with the proper Target_Name.
	(Initialize_Project_Path): Add <gnat_root>/<target_name>/lib/gnat
	search path.
	(Get_Path): Add Target_Name parameter. Call Initialise_Project_Path
	with the proper Target_Name.
	* prj-conf.adb (Get_Or_Create_Configuration_File): Pass Target_Name to
	Part.Parse routine.
	(Parse_Project_And_Apply_Config): Likewise.
	* prj-makr.adb (Initialize): Pass empty Target_Name to Parse routine.
	This is fine as this part of the code is supporting only native
	compilation.
	* prj-pars.adb (Parse): Pass empty Target_Name to Parse routine. This
	is fine as this part of the code is supporting only native compilation.
