Alter your Generic.

generic
   type Element_Type is private;
   with procedure Display_Element (Item : in Element_Type);
   with function "<"(Left, Right : Element) return Boolean is <>;
   with function "="(Left, Right : Element) return Boolean is <>;
package Linked_Lists_Generic is
-- ...
    Function ">=" (Left, Right) Return Boolean is
      ( not (Left < Right) );
end Linked_Lists_Generic;

If you're not using Ada 2012 then you'll have to put the implementation 
of >= in the body.
