This is not darwin specific: see
https://gcc.gnu.org/ml/gcc-testresults/2015-01/msg01376.html.
At https://gcc.gnu.org/ml/gcc-testresults/2015-01/msg01372.html, I see
=== libffi tests ===
Running target unix
=== libffi Summary ===
# of expected passes 2204
i.e., no unix/-m32.
Should we open a new PR for that?
