[FFmpeg-cvslog] configure: use -r option for pr when listing enabled config options.

[Konstantin Pavlov]

ffmpeg | branch: master | Konstantin Pavlov <thresh at videolan.org> | Thu Mar 17 10:11:14 2011 +0000| [fda299f0d01c1691625180786a01b01065df7156] | committer: Mans Rullgard

configure: use -r option for pr when listing enabled config options.

This fixes ugliness when configure outputs its (empty) results on HPUX
(maybe some other UNIXes too):

Enabled indevs:
pr:  -- empty file
