I did the above.
After "make dist", octave-4.1.0+.tar.gz was generated in build directory.
The archived file contained the documentation.
Then I executed mxe-octave using this octave-4.1.0+.tar.gz.
make zip-dist
Build of default-octave step was stopped.
/bin/bash run-octave --norc --silent --no-history

As you said, run-octave is meaningless because this is cross-build.
How can I do ?
