[xenial] backtrace gives python error on i386

[Sebastien Bacher]

That's using i386, using "backtrace" gives those errors

"Traceback (most recent call last):
  File "/usr/share/gdb/python/gdb/FrameDecorator.py", line 97, in function
    if not isinstance(self._base, gdb.Frame):
SystemError: <built-in function isinstance> returned a result with an error set

#1 0xffffffff in OverflowError: Python int too large to convert to C long"

can't reproduce from an amd64 kernel, though this patch might be worth a try
