[opam-devel] global installation with opam

> I think having a special "global" switch could makes sense and could be implemented without too much hassle. Need to special case https://github.com/ocaml/opam/blob/master/src/core/opamPath.ml to use global paths. Requiring the user to install ocaml and ocamlfind only could help (so we need to implement a the detection of an "external" ocamlfind) as we don't need to support other external ocaml libs (which can become a pain when you want to upgrade ...).

to be more complete: this will make system compiler and ocamlfind updates more complicated, but I think that Louis is already looking at this for the "compiler-as-a-package" stuff.
