PATCH: PR other/59055: gcc.texinfo warnings

["H.J. Lu" <hongjiu dot lu at intel dot com>]

There are 2 almost idential menus. The only difference is one doesn't
have

* Option Summary::      Brief list of all options, without explanations.

* Submodel Options::    Specifying minor hardware or convention
* variations,
                        such as 68010 vs 68020.
* Code Gen Options::    Specifying conventions for function calls, data
* layout
                        and register usage.
* Environment Variables:: Env vars that affect GCC.
* Precompiled Headers:: Compiling a header once, and using it many
* times.

It leads to

Is the second menu really needed? This patch removes the second menu.
OK to install?
