That seems like an ugly solution if you have to do it regularly (which
is how I interpret the task you're describing).  I'd write a small
wrapper in C (but you could do it just as easily in Python, etc) that
ran the make after setting up the file descriptors/pipelines as required
and then exited with the make status.  It's a couple of minutes using
the standard templates and eleventy gazillion times simpler than trying
to beat shells into submission.

Cheers, Greg
