  Righto.  Well, you want to use a '+' at the start of the command lines that 
invoke the test controller, and make will then pass it all the MAKEFLAGS, 
including a variant -j option with fds for the read and write sides of the 
jobserver pipe.

  Paul's website is down at the moment, but have you read the jobserver page 
there?  It's available through web archive:
