Title:
  [SRU] boinc-client crashes when started with core dump on Xubuntu
  22.04

Status in boinc package in Ubuntu:
  Fix Released
Status in boinc source package in Jammy:
  Confirmed

Bug description:
  [ Impact ]

  boinc-client is completely unusable on older CPU which does not have avx like a Celeron CPU.
  It will crash immediately if run on old CPU, but will run without any problem on newer CPUs.

  [ Test Plan ]

  It should be done on both types of CPUs, one which has AVX, and one which does not have AVX.
  If using qemu then "-cpu Conroe-v1" will emulate Celeron CPU without AVX.

  Confirm with the command "lscpu" and check the flags if "avx" is
  listed or not.

  Commands to execute for testing on both CPUs:

  1. Install boinc
  2. Execute "boinc" from a terminal

  If the package is not fixed then it will fail to start.

  [ Where problems could occur ]

  There is no change in the code and is only modifying debian/rules so
  that the built binary does not have any machine instruction for AVX.
  It will result in a different executable machine code but chances of
  regression due to this is very low.

  [ Other Info ]

  This change is from Debian and is part of Ubuntu from Manctic onwards. There has been no reported regression due to this change.
  The Debian change is at: https://salsa.debian.org/pkg-boinc-team/boinc/-/commit/a0611c2bc86864428337b07b382e4d5cf823b95d
