You'll need to triple-check then.  It's not physically possible for GNU
make version 4.3.91 to generate that error message.  Somehow your build
system is still running some other version of make; it's probably a
good idea to figure that out and see what version it actually is. 
Maybe add a line to your recipe that runs make with --version to see
what's happening.

The code in GNU make 4.3.91 says:

  if (outfile == 0)
    OSS (fatal, NILF,
         _("fopen: temporary file %s: %s"), newnm, strerror (errno));

My suspicion is that you're running the old, broken version of GNU make
that Apple ships with its Xcode environment.
