It's mostly useful on platforms where dynamic libraries are not
implemented. You can then at least create your own ocamlrun that is able
to run all your programs. There is a companion switch -use-runtime which
instructs to use a certain runtime when linking a program.

On platforms with dynamic libraries it is close to useless. (Well, if I
remember correctly, I'm using this feature in the GODI bootstrap to get
a distributed bytecode executable running on the local system, w/o
needing a complete ocaml infrastructure, but this is certainly a very
special case.)
