OK, here is a new version using Makefile.def and generic targets in
Makefile.tpl that get expanded by autogen.  I also added the
check-obj-c++ and check-gcc-obj-c++ targets that David Ayers asked about,
check-obj-c++  tests both the objc and libstdc++-v3 runtime libraries in
addition to the obj-c++ compiler.

OK to checkin?
