GDB 12 has some welcome behaviour changes, especially around floating point values. See 574110 for more details on that.

There is a gerrit which is WIP on updating the CDT tests to work with GDB 12 that hasn't been integrated yet.

GitHub actions recently changed ubuntu-latest to being Ubuntu 22.04, which means our tests now run against GDB 12 and we get lots of false negative test results.

Use Ubuntu that contains GDB 10
381f9ae 
Until we are ready for GDB 12 in the testsuite, run the GHA
checks against GDB 10 by chaning base OS to Ubuntu 20.04
instead of latest (which recently changed to 22.04)

Update tests for GDB >= 12 for change in formatted values
a1c52b0 
From GDB news:

print
  Printing of floating-point values with base-modifying formats like
  /x has been changed to display the underlying bytes of the value in
  the desired base.  This was GDB's documented behavior, but was never
  implemented correctly.

This commit updates the tests to accomodate GDB's change.

Fixes eclipse-cdt#210
