I probably should have mentioned... Here are the docs on
sys_lib_dlsearch_path_spec
(http://www.delorie.com/gnu/docs/libtool/libtool_71.html):

  Variable: sys_lib_dlsearch_path_spec

      Expression to get the run-time system library search path.
      Directories that appear in this list are never hard-coded
      into executables.

But I'm not quite following what needs to be done or how it should be handled.
