Enable -Wpointer-sign by default.
This enables -Wpointer-sign by default.
I've checked that --enable-targets=all builds fine with the following
as --host, on x86_64 Fedora 17 --build:
x86_64 GNU/Linux
i386 GNU/Linux
i386 MinGW-w64
i386 msdos/djgpp
OK?

* configure.ac (build_warnings): Replace -Wno-pointer-sign with
-Wpointer-sign.
* configure: Regenerate.

* gdbint.texinfo (Misc Guidelines) <Compiler Warnings>: Replace
-Wno-pointer-sign text with text on -Wpointer-sign.
