    How does this work ? Do I put my changes in building.texi ?

If it is short, yes.  Otherwise write a separate file.

     Do I install the
    patch or submit it to the mailing list/you. Can it have references to gdb 
info
    pages or only ones in the emacs distribution ?

Referring to the GDB manual is very useful.
The Texinfo manual says how to do that.
