[Bug 1970521] Re: [SRU] boinc-client crashes when started with core dump on Xubuntu 22.04

[Mauricio Faria de Oliveira]

** Description changed:

  [ 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.
  
+ There does not seem to be performance-critical code in the boinc client
+ or boinc library (which is the API provided for the boinc _applications_,
+ which are performance-critical path; the API is not a high-performance lib).
+ 
+ Thus, removing AVX from the package, even for the API, would not seem to
+ cause a performance regression for working/avx-capable processor models.
+
