[PATCH] Display var_zinteger as signed

["Andrew Burgess" <aburgess@broadcom.com>]

Currently the behaviour of var_zinteger variables is to print as 
unsigned, so,

(gdb) set debug infrun -5
(gdb) show debug infrun
Inferior debugging is 4294967291.

With the patch it is displayed as -5.


Cheers,
Andrew
