w00t!  Thanks for the help.  A full fix should be in 4.4.1 which I hope
to release this week or weekend.

Just as a little icing on the cake, I tried my cmake build of doxygen, and again it went through with no jobserver warnings.

Sorry, I spoke too soon. I just went back to my original use case, in which I used the TeX Live "Build" script instead of directly invoking make, and I again got the jobserver warning. [This is the use case in which I got a hang when using a fifo instead of a pipe.]

I'm attaching that script so you can see exactly how "make" is invoked in a subshell. I'm also attaching my build log up to the point of the warning and the Makefile in the ft-build directory in which the warning occurred. I've previously sent you the top-level Makefile.

Let me know if you need anything else.
