+Description: Make the build reproducible
+  Whilst working on the Reproducible Builds effort [0], we noticed
+  that libffi-platypus-perl could not be built reproducibly.
+  .
+  This is because it rendered JSON without calling "canonical" to ensure
+  determinsitic sorting which ended up in a "config.json" file.
+  .
