Test LD_LIBRARY_PATH_FDS by linking a binary that requires a shared library that isn't in any of the usual search paths. Ensure this fails when we don't supply LD_LIBRARY_PATH_FDS or we pass invalid information in it. Ensure it works when we pass the correct directory in various places in the variable.
