It took repeated `make`s to finally build. Never failed repeatedly in the same

Decreasing the J made it happen less, but maybe that's just because it's 
compiling less? Without a reliable failure case I could not identify it further.

It's *way* more likely that there's a bug in the dependency ordering of some modules; a highly parallel build would hit the bug by trying to compile a module before its prerequisite. (This also means why running make multiple times doesn't help, and actually might make the bug "go away" by compiling the prerequisite.)
