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

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