  3. Build suffixed shared runtimes 

    New names for libcamlrun_shared.so and libasmrun_shared.so without the
_shared suffix and using the target triplet and runtime ID. Both ocamlc
and ocamlopt explicitly recognise `-runtime-variant _shared` and select
the correct name.

Symbolic links for libcamlrun_shared.so and libasmrun_shared.so to allow
any C programs which linked against the the output of `-output-obj` to
continue to work.

  5. Add runtime suffixes to bytecode stub libraries 

    ocamlc -dllib-suffixed appends the runtime's host triplet and bytecode
runtime ID to the supplied name when searching for the DLL, and records
the base name only in .cma / executable files.

ocamlmklib -suffixed instructs ocamlmklib to use -dllib-suffixed when
generating .cma files instead of -dllib.

The effect is that stub libraries built this way have names which will
be unique for a given configuration of OCaml and so will be ignored by
other runtimes.
