Greetings,

I had a dev complain about losing stdio output in a Xenomai app, and
had never looked at rt_printf() and friends before.  I had
problems attempting to use --print-buffer-syncdelay=1 to reduce the
delay to 1(ms), I found that my programs started complaining about an
invalid switch.  Found that cobalt_help() was out of sync with the
actual switch name definition --print-sync-delay.

Here's a lame attempt at a patch.

Regards,
Steve
