[Bug translator/12138] sdt_misc.exp fails most ptr types on i686


http://sourceware.org/bugzilla/show_bug.cgi?id=12138

The test isn't very helpful about diagnostics, but I'll pick the first FAIL:

>From sdt_types.c:
  char *ptr_char_var = &char_var;
  STAP_PROBE2(provider,ptr_char_var,ptr_char_var,&char_var);

>From sdt_types.stp:
probe process(@1).mark("ptr_char_var") {
  if ($arg1 != $arg2)
    printf("FAIL: ptr_char_var\n")
  else
    printf("PASS: ptr_char_var\n")
}


$ stap -c ./sdt_types.x -e 'probe process("./sdt_types.x").mark("ptr_char_var")
{ printf("%p %p\n", $arg1, $arg2) }'
0xffffffffbf81541a 0xbf81541a

Along the way, the sign got extended...
