Currently running gdb_mbuild pretty much for the first time, and
disovering lots of builds failures, mostly because of -Werror. Here
is a fix the one warning in one of the core files. I think the other
ones are in target dependent files.

        * event-top.c (gdb_setup_readline): Add missing type in extern
        declaration.

Fixes the following compiler warning:

        event-top.c: In function `gdb_setup_readline':
        event-top.c:1113: warning: type defaults to `int' in declaration of `batch_silent'

Here is where the variable is defined:

        main.c:int batch_silent = 0;

Tested on x86-linux, no regression in the testsuite. I'm committing
this under the obvious fix rule. I think it's pretty obvious.
