Heelo Peter, I ran into exactly that problem when trying to build a gcc for m68k-coff. I added --with-newlib to the config options fot the gcc configure, and the errors disappeared, but I didn't test c++ up to now. I think there is a bug in the gcc-2.95.3 build for m68k targets. For a standard build, you end up with a compiler setup with missing board support libraries, so a link fails with missing symbols and configure says the compiler is not working. If you don't need c++, you may set languages to c only. In this case the libiberty is not needed and won't be built.
