[FFmpeg-devel] [PATCH V4 2/2] configure: replace 'pr' with printf since busybox does not support pr

[Guo, Yejun]

It is part of change from https://trac.ffmpeg.org/ticket/5680 provided
by Kylie McClain <somasis at exherbo.org> at Wed, 29 Jun 2016 16:37:20 -0400.

That change contains two parts, in function log_file and in function print_in_columns.

The second part is not good, so I have send out a new patch for print_in_columns.

As for the change in the first part, it is good. Just to make the whole thing completed,
i send out this patch to copy exactally the change in function log_file.
