[bitbake-devel] [PATCH] knotty: Ensure the progress bar shows on stdout

[Richard Purdie]

I can understand why some programs would want the progress on stderr so
that real output can be captured on stdout. This is confusing for bitbake
since we don't show a progress bar at all in non-interactive cases.

Therefore make sure the progress bar goes to stdout, not the stderr default.
