Don't print symbol on address 0x0

We see the following fails on arm-none-eabi target,

print (void*)v_signed_char^M
$190 = (void *) 0x0 <_ftext>^M
(gdb) FAIL: gdb.base/exprs.exp: print (void*)v_signed_char (print
(void*)v_signed_char)

GDB behaves correctly but the test assumes there is no symbol on
address 0x0.  This patch is set print symbol off, so that tests below
can match the address only.
