Instead of using a single -cclib to pass three C libraries at the same
time (which you noted doesn't work), you should use -cclib three
times, once for each library:

camlc -custom -linkall -o ocamltktop -I ../support \
      -ccopt -L../support -cclib -lcamltk -ccopt "" \
      -cclib "-ltk8.3" -cclib "-ltcl8.3" -cclib "-ldl "
      -ccopt "-L/usr/X11R6/lib" \
      -cclib "-lSM" -cclib "-lICE" -cclib "-lX11"  -cclib "-lm" \
      toplevellib.cma camltk.cma topmain.cmo

Since there could be a library with a space or a single quote in its
name, ocaml does the correct thing. How is it supposed to know that
your library is not called "SM -lICE -lX11 -lm"? I admit only a crazy
person would create such a library, but that is irrelevant.
