I don't know the answer but one thought that occurred to me: are you
using Apple's frozen-in-time GNU make?

$ make -v
GNU Make 3.81
Copyright (C) 2006  Free Software Foundation, Inc.

Could it have bugs that were later fixed?  On the other hand, I build
PostgreSQL myself quite regularly on a Mac with that version and -j8
and I have not seen that problem.
