Patch to correct unexpected run path handling for dynamic libraries

When linking dynamic libraries (as opposed to executables), gnatmake adds run
path information regardless of whether '-R' was provided. This can be confirmed
with a simple GNAT project like:

project Without_rpath is
   for Library_Name use "without_rp";
   for Library_Kind use "dynamic";
   for Object_Dir   use "obj";
   for Library_Dir  use "lib";
   for Source_Dirs  use ("src");

   package Builder is
      for Default_Switches ("Ada") use ("-R", "-v");
   end Builder;
end Without_rpath;

The attached patch corrects this behaviour.
