I've made the script executable.  Thanks for catching this.

I've added notes to this effect to EGLIBC.cross-testing and to
cross-test-ssh.sh's help message.  In general, I think we simply want
to say that one needs ordinary ssh working smoothly and quietly before
trying the wrapper, and then one needs to use the wrapper in the same
way.

:) I wrote a similar script in order to develop the instructions.
However, I think providing a script which can be used in all the
different circumstances and arrangements people might encounter in
cross-development seems like a large and complicated task --- the
variations being the source of the complexity, not the essential job
to be done.  So (without more budget :) ) I don't think we should try
to offer a build script as part of EGLIBC itself.  Providing clear
instructions for a simple arrangement, which people can adapt to their
purposes, seems a better strategy.

Thanks very much for trying these --- I'm glad to hear they worked for
you, once the details were ironed out!  If you run into any other
difficulties, please post.
