[FFmpeg-cvslog] configure: make assignment of variable to '=' explicit

[Ganesh Ajjanagadde]

ffmpeg | branch: master | Ganesh Ajjanagadde <gajjanagadde at gmail.com> | Sun Sep 13 02:26:04 2015 -0400| [6d1801b5aaf9b384e13adffff4ab5886dae65693] | committer: Timothy Gu

configure: make assignment of variable to '=' explicit

op== is confusing, as it may easily be mistook for an equality check,
while in reality it is doing an assigment to '='.
This patch has the additional benefit of cleaning up 2 warnings from shellcheck.net.
