Fix a parallel make race condition by swapping the order of -I directories.
...
The .cmi files are generated in $(ObjDir) and then copied to $(OcamlDir).
The ocamldep output references the .cmi files in $(ObjDir), so make kicks
off a dependent compile as soon as the local copy is generated. If the
copy to $(OcamlDir) is not complete at that point, the compiler will read
the partially copied file and complain about a "Corrupted compiled
interface". Searching $(ObjDir) first avoids this.
