The binutils for target will only build some of the binutils libraries.
They are needed to build stuff like oprofile, and have to match the
version of binutils used for in the toolchain. That's why there is the
option.

To build the complete binutils to run on the target (eg. ar, ld...)
means to build a cross-native toolchain, which is not currently
supported by crostool-NG ( although I'm working on it, but there's
only 24h in a day! ).

As said above, not currently supported. Sorry... :-/
