re PR testsuite/23609 (all obj-c++ execute tests fails with the GNU runtime)

        PR testsuite/23609
        * lib/obj-c++.exp: Include target-libpath.exp.
        (obj-c++_link_flags): Look for the GNU libobjc library
        and set the library path to include it.
        Don't manually set LD_LIBRARY_PATH (etc.) but call
        set_ld_library_path_env_vars instead.
        (obj-c++_target_compile): Don't set library path or
        linker flags because they are already set correctly
        in obj-c++_link_flags.
