/* Provide a LINK_SPEC appropriate for Linux.  Here we provide support
46
   for the special GCC options -static and -shared, which allow us to
47
   link things in one of these three modes by applying the appropriate
48
   combinations of options at link-time. We like to support here for
49
   as many of the other GNU linker options as possible. But I don't
50
   have the time to search for those flags. I am sure how to add
51
   support for -soname shared_object_name. H.J.
