Thanks, Marco.  As expected, that fixes the problem for my test case
(building TeX Live).  Obviously it would be better if the make
developers would provide a configure option to use a pipe for the
jobserver, but this is a good workaround if they don't.

Does it actually do a parallel build?  I've quickly tested a cmake based
project with it and it completely serializes the build.  Reverting to
4.4 resolves that problem.

It does for my build of TeX Live.  I just tried 'make -j13 check', and I saw many make processes and many sh processes running at once.  [But I'm currently testing a self-built make 4.4.0.91.]

Definitely parallel jobs visible in top with make 4.4.0.90-1
