* lisp/info-look.el (makefile-automake-mode): New setups, looking in

automake manual, then makefile-mode.
(makefile-mode): Remove automake manual, have it just in
makefile-automake-mode since there's various things different or
not relevant to plain make.
(makefile-mode): Remove "other-modes" non-existent automake-mode,
believe a hypothetical automake-mode would go to makefile-mode,
not the other way around.
