[PATCH] Fix the list of directories searched for object files and libraries.

[Cedric VINCENT <cedric dot vincent at st dot com>]

Without this patch, the following command is terminated due to an
invalid memory reference (SIGEGV):

    ld -m elf_i386 -L /opt/XXX/lib -lfoo bar.o

Technically, this is due to how the function "open_along_path2"
handles the list of directories searched for object files and
libraries:

    open_along_path2 ([...], pathelement *path)
    {
      [...]
      firstp = path;
      do
        {
          [...]
          path = path->next;
        }
      while ([...] && path != firstp));
      [...]
    }

The function "open_along_path2" assumes the field "next" of the last
element points to the first element.
