Also search the bare ocaml standard library path for llvm bindings.

Ubuntu ships the llvm bindings in /usr/lib/ocaml/llvm/ but Fedora
is installing them directly in /usr/lib/ocaml so we need to check
there as well.

The patch is untested; Fedora 14, the current beta, includes llvm 2.7.
It does add an unnecessary -I directive, but should at least have a
better chance of working on Fedora 15.
