libppx-compare-ocaml-dev binary package in Ubuntu Focal s390x

 Ppx_compare is a ppx rewriter that derives comparison and equality
 functions from type representations. The scaffolded functions are
 usually much faster than ocaml's Pervasives.compare and
 Pervasives.(=). Scaffolding functions also gives you more flexibility
 by allowing you to override them for a specific type and more safety
 by making sure that you only compare comparable values.
