bytecode support

[edwintorok]

I'm using mtime with ocamlopt but it would be nice to have mtime working with the toplevel or bytecode too.
Apparently it tries to load rt as a bytecode library and not the system librt.so:

$ ocamlc -version
4.02.3
$ ocamlfind ocamlc -package mtime.os x.ml -linkpkg  -verbose
Effective set of compiler predicates: pkg_mtime.os,autolink,byte
+ ocamlc.opt -verbose -I /home/edwin/.opam/4.02.3/lib/mtime/os /home/edwin/.opam/4.02.3/lib/mtime/os/mtime.cma x.ml
File "x.ml", line 1:
Error: Error on dynamically loaded library: dllrt.so: dllrt.so: cannot open shared object file: No such file or directory
ocamlc.opt returned with exit code 2

$ utop
[...]
utop # #require "mtime.os.top";;
Cannot load required shared library dllrt.                                                                                                                                  Reason: dllrt.so: dllrt.so: cannot open shared object file: No such file or directory.                                                                                      File "/home/edwin/.opam/4.02.3/lib/mtime/os/mtime_top_init.ml", line 1:

Mmmmh sorry about that. This comes at the right time since I'm working on finishing ptime_clock and was copying that build system. I tried to provide a fix could you please try to:

opam pin -kgit mtime https://github.com/dbuenzli/mtime.git
cp $(opam config var mtime:doc)/min.ml /tmp/
cd /tmp
ocamlfind ocamlc -package mtime.os -linkpkg -o min.byte min.ml
./min.byte 
ocamlfind ocamlopt -package mtime.os -linkpkg -o min.native min.ml
./min.native 

and confirm me that this now works (I tried on Darwin and Ubuntu 14.04 64bits).

Thanks, works on Debian Jessie.

Not sure if Linux is the only OS that needs -lrt though, but I don't have a Solaris machine to test now.

I'll make a release soon. Just fixing other parts of the build system (#1).
