Title:
  crash reports Illegal instruction w/ newer binutils

Status in crash package in Ubuntu:

Bug description:
  crash 7.2.6-1ubuntu1 now fails on arm64 w/ an Illegal instruction:

  $ sudo crash -st /usr/lib/debug/boot/vmlinux-$(uname -r) /proc/kcore
  Illegal instruction

  The previous version of crash was 7.2.6-1build1. While there are no
  differences in the source code (just an autopkgtest update), it did
  not hit this:

  $ sudo crash -st /usr/lib/debug/boot/vmlinux-$(uname -r) /proc/kcore
  Fri Jan 10 19:31:59 2020

  I've verified that the significant difference is with the version of
  binutils used to build crash.

  2.33.50.20200107-1ubuntu1 - Illegal instruction
  2.33.1-6ubuntu3 - OK
  2.32.51.20190905-0ubuntu1 - OK
