Comment (by mojca@…):

 I made a horrible commit in r151998 that hopefully fixes the build for
 Sierra and hopefully doesn't break builds on older machines.

 The initially proposed changes that affect all perl subports don't work
 properly for older perls. Older perls most likely don't compile on Sierra
 either. I will do a cleanup of the main port (or #50512), but only once
 the changes get some proper diagnosis, testing and fixes. For now I just
 wanted to make sure that Sierra users could install the ports that still
 depend on 5.22 (#52081).

 I will keep the ticket open until perl5.16 - perl5.20 gets proper
 treatment.
