Comment (by mojca@…):

 I attached a patch that increases the revision of all perl versions (other
 than 5.24) and:
 * removes the 10.3 target
   * this should fix the build problem on Sierra
   * I don't know whether we still need to add `{-Dld="env
 MACOSX_DEPLOYMENT_TARGET=$MACOSX_DEPLOYMENT_TARGET $CC"}`
 * changes location of `perl5.16`
 * uses `-Dcppflags="$CPPFLAGS"` instead of `-Acppflags="$CPPFLAGS"`
 * removes `fix-ld-modification.patch` (but includes its contents in the
 new patch)
 * cleans up the patches a bit (I had problems with constantly changing
 line numbers; I changed the patches so that they don't change the number
 of lines unless necessary)

 I would like an "OK" from at least one Sierra user and David (other
 testers welcome as well) before committing this.

 And yes, I keep #50512 in mind as well.
