/* Provide a LINK_SPEC appropriate for Linux.  Here we provide support

   for the special GCC options -static and -shared, which allow us to

   link things in one of these three modes by applying the appropriate

   combinations of options at link-time. We like to support here for

   as many of the other GNU linker options as possible. But I don't

   have the time to search for those flags. I am sure how to add

   support for -soname shared_object_name. H.J.

   I took out %{v:%{!V:-V}}. It is too much :-(. They can use

   -Wl,-V.

   When the -shared link option is used a final link is not being

   done.  */
