So that's quite weird, because the native Mac ld uses one dash, but
an _underscore_ in the option name: -export_dynamic. The patch was
wrong -- the change was needed but it was not quite right. Not sure
how this ended up in the tree!

Fixing this fixed everything. The correct patch is this, and please
apply it to the trunk for 3.14.2 or whatever:

--- configure.ac.~1~	2016-11-06 07:01:27.000000000 -0500
+++ configure.ac	2017-01-13 16:12:50.000000000 -0500

Note what you suggested doesn't work:
