	10. KC_TCL_STATICPKGS
		Set this variable to the value "1" to attempt to force the
		packages included in the "pkgs" directory of Tcl 8.6+
		to be compiled statically

	11. KITCREATOR_STATIC_KITDLL
		Set this variable to the value "1" to build a static KitDLL.
		This only has an affect when KITCREATOR_PKGS specifies that
		"kitdll" is to be built (e.g., KITCREATOR_PKGS='kitdll')
