configure: Comment out Ruby, Java, Haskell detection.

We will not be implementing bindings for Ruby, Java or Haskell
unless someone pitches in to do the work.  Therefore comment out
the code which detects these languages in the configure script.

(This leaves OCaml, Perl, Python, which we will be writing
bindings for).
