Yes. Look at the output of:
 $ ct-ng list-steps

Long story put short: that does not work. Besides, building libstdc++
requires the complete C library (newlib in our case), and that is
only built later.

Not much. But I'd appreciate if you could confirm:
- start from crosstool-NG 1.7.0
- build your toolchain, enable C++ support
- when it is installed:
    cd targets/arm-unknown-eabi/build/build-cc-core-baremetal
    make all-target-libstdc++
    make install-target-libstdc++

With that, can you check that the toolchain is now capable of C++?
