You could put this in ~/.gdbinit:

handle SIGTSTP nopass

Its explained in DEBUG:

    The src/.gdbinit file in the Emacs distribution arranges for SIGINT
    (C-g in Emacs) to be passed to Emacs and not give control back to GDB.

Actually this only seems to be necessary when Emacs is running in a

In general, it can't, for the reason above.
