I had a quick look, but I'm not sure of the interest of a specific
ocamlbin parameter, whereas you may as well just use PATH:

if test -z "$CAMLC"; then
    AC_MSG_ERROR([objective-caml compiler not found, check your PATH])

Standard macros, such as AC_PROG_CC, also relies on default PATH, and
don't provide additional options for supplying program specific one.

You can't disable existing ones. However, it don't see anything C/C++
specific apart environment variable among them, and they don't really
hurt anyway.

For new ones, you have AC_ARG_WITH and AC_ARG_ENABLE, fur subtle
semantic differences.
