Since quite a while ago (a month or so I guess), I had read a blog post
by OCamlPro about generating static PIE with OCaml.

The first project on where I have tried doing was Logarion, and
afterwards bumpmap-tool, each using a different build system.

In the first case, I had to add the field `'(flags (:standard -cclib
-static))'` to the `cli/dune` file and rebuilt with `dune build`.

As for the second case, I added `-cclib -static` to the `ocamlopt` flags
in the command line and rebuilt.

I ran the ldd command in both (test was done on Alpine Linux, a
musl-based distro) only to have this output:
	- /lib/ld-musl-x86_64.so.1: (insert executable name here): Not a valid dynamic program

Which means that it does actually work, but I'm not sure whether it
could work for bigger projects.

I think that's all I've got to say here.
