Title:
  Enable x86 retpoline options by default

Status in gcc-7 package in Ubuntu:
  Won't Fix

Bug description:
  For Ubuntu 18.04 LTS, the x86 retpoline options (-mindirect-
  branch=thunk and -mfunction-return=thunk) should be enabled by
  default.

  For problematic packages, -mindirect-branch=keep and -mfunction-
  return=keep can be used to disable retpolines.
