[Libguestfs] [libnbd PATCH] Fix building with for ocaml < 4.06.0
Signed-off-by: Martin Kletzander <mkletzan(a)redhat.com>

Notes:
This is the simplest solution suggested to me by Rich and it works.
Most of autotools are not friends with me, so the other approach I tried, with
requiring at least OCaml 4.05.0, having this fix in only for OCaml < 4.06.0 and
properly detecting and reporting that, was a bit ugly.
You can see the configure.ac part of it here: http://ix.io/1L0o
If that is preferred, then I can send that one instead.
