[PATCH] Ignore -o (output_name) when in server mode

Reported by ehrhardt@de.ibm.com.

It doesn't make a lot of sense to allow directories inside the session
private directory, and we currently do not handle multiple directories
inside the generated dir. So just ignore that option and inform the user.
