I think you and Joseph are right.  I need to define
gcc_cv_ld_static_dynamic and friends to get -static-libstdc++ and
-static-libgcc to work properly.  The problem is that when I do this
it gets used for -lunwind as well as libgcc and libstdc++.  I use the
HP-UX system libunwind and that comes as a shared library only.  So I
need to have some kind of an override so that even when
USE_LIBUNWIND_EXCEPTIONS and HAVE_LD_STATIC_DYNAMIC are set I don't try
to use a static unwind library.  I am testing with a hack right now to
verify that it all works when I do override this part of the driver to
use a dynamic libunwind even with -static-libgcc and -static-libstdc++.
