If I'm right, the solution would seem to be to disable the use of

Never mind. My speculation is leading nowhere. I just had 5
successful builds followed by a hang in the 6th attempt. I guess I
just have to continue using a pipe for my TeX Live builds.
The latest release (GNU Make 4.4.1) uses pipes for jobserver on both
Cygwin and Hurd, which both seem to have problems emulating POSIX-style
FIFOs.
Did that change not work for you, or did you by-hand force the
jobserver to use FIFOs for these tests?
We forced it to use FIFOs by configuring with -DJOBSERVER_USE_FIFO=1.
