  # Statically linked ECL with statically linked dependencies.

  # context will require figuring out cross compilation (for
  # pkgsStatic), so we're gonna use this override for now.
  #
  # Note that ecl-static does mean that we have things
  # statically linked against GMP and ECL which are LGPL.
  # I believe this should be alright: The way ppl are gonna
  # interact with the distributed binaries (i. e. the binary
  # cache) is Nix in the depot monorepo, so the separability
  # requirement should be satisfied: Source code or overriding
  # would be available as ways to swap out the used GMP in the
  # program.
