     * Notes:
     *
     * PL_initialise wants to know the path to the binary that has libpl.a
     * linked into. It tries to load the binary as a prolog resource file.
     * If this fails it will practically skip parsing most of the command
     * line, including our options to silence output and limit the size of
     * the various stacks.
     *
     * In our case, libpl.a is linked to libprolog.so and not to the main
     * binary. Hence we first need to find the path to libprolog.so and then
     * pass this in as argv[0] to PL_initialise. Ugly, I know... but necessary
     * unless we link statically.
     *
     *
     * Notes #2:
     *
     * This is unarguably a linux-specific hack. An alternative would be
     * a GLIBC-specific hack using dl_iterate_phdr(3) to iterate directly
     * through the list of shared objects loaded into us. This would have
     * the benefit of not needing to open and parse /proc entries.
     *
     * Notes #3:
     *
     * Stand-alone precompiled prolog files include a copy of the interpreter
     * itself. Using one could be an alternative to avoid this problem
     * altogether.
