I would recommend:
   f1.addStep(shell.ShellCommand, command="make smoke | grep --line- 
regexp -F 'All tests successful.'")

But this will cut off the entire log, which is probably undesirable.   
Possible workaround:
   f1.addStep(shell.ShellCommand, command="make smoke >stdout; cat  
stdout; grep --line-regexp -F 'All tests successful.'")

If you really want to do it on the BuildBot side, you need to  
subclass shell.ShellCommand and override one of its methods (can't  
remember which) to properly set the failed state whenever that  
particular line didn't appear in the output.

HTH.  Cheers,
