I've added the above tasks and they are reported to have been 
completed successfully in the Cirrus summary.
However, on a closer look I can spot multiple failures or 
files/directories which can't be found.
- Some 12 failed tests as well as 10 unresolved test cases in the 
unittest step.
- The build package step failed with: cd ./libcc1: no such file 
or directory.
