Romain Naour 7a0fa5b19b package/gdb: fix gdb python support with python 3.8
CPython 3.8 has added a new Syntax Warning that print
a waring at runtime while unsing gdb python support.

$ gdb -ex "python import os"
/usr/share/gdb/python/gdb/command/prompt.py:48: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if self.value is not '':
/usr/share/gdb/python/gdb/command/prompt.py:60: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if self.value is not '':

Subject: [PATCH] Fix incorrect use of 'is' operator for comparison in
python/lib/gdb/command/prompt.py
The 'is' operator is not meant to be used for comparisons. It currently working
is an implementation detail of CPython. CPython 3.8 has added a SyntaxWarning
for this.
(cherry picked from commit b6484282f85bf7f11451b2441599c241d302ad9d)
[Romain: backport to gdb 8.x]
