Paul did fix some progress bar issues which were one cause of this.
pseudo is another cause and we've not gotten to the bottom of the
pseudo issue :(. It writes to the console unknown to knotty so there
isn't much we can do about it from the bitbake side, it should be a)
making it clear the messages come from psuedo and b) likely going to a
logfile, not the main console.
