That's a partial solution, but would probably be enough for these few
cases. For example, it doesn't detect when you have libxxx.a file with C++
objects in it.

Also, it leaves out the dependency on libstdc++.  linking everything with
c++(1) is a subset of adding to LDADD/DPADD.  The LDADD is taken care of,
but the DPADD of ${LIBSTDCPLUSPLUS} is missing.  Only ${LIBC} is depended on.

It might be better to have a switch to specify c++ linking.

Or we could just leave it the way it is.

Cheers,
-Peter
