C++ bootstrap of GCC - still useful ?

OK, so the only needed Makefile change is to gcc-interface/Make-lang.in:

I'm not sure about the long-term interaction with -static-libgcc here, but this 
works currently on Linux so let's keep it for now.

And this means that the initial version adds superfluous extern "C" blocks, I'm 
going to clean it up.
