New target (check-cpp) to avoid Makefile.direct parallel build issue

* Makefile.direct: Add comment about check-cpp.
* Makefile.direct (test_cpp): Replace dependency on "c++" with
"gc_cpp.o base_lib"; link with gc_cpp.o directly.
* Makefile.direct (check-cpp): New target (same as c++-t but do not
depend on c++ target and pass no arguments to test_cpp).
