Comments there refer to libgfortran/config/fpu* – yeah, it is not IEEE module itself, but those config files enable building IEEE module, and Darwin is not currently among supported systems. Unless, of course, comments are off: https://github.com/gcc-mirror/gcc/blob/7a65ab6b5f38d3018ffd456f278a9fd885487a27/gcc/testsuite/gfortran.dg/round_4.f90#L17-L19
Rounding modes are supported in Apple libm, of course, regardless of what gfortran config has, but the test case for 16-byte should still fail with IBM long double.
