Make clean doesn't really clean everything

My system updated to a new ocaml version and I had to rebuild obc.

Usually a make clean and a make install would suffice but in this case I had to remove some files manually, because:

File "config.ml", line 1: Error: ../yacc/yyparse.cmi is not a compiled interface for this version of OCaml. It seems to be for an older version of OCaml.
