[Jean-Yves Avenard]

ffmpeg | branch: master | Jean-Yves Avenard <jyavenard at mythtv.org> | Sun Oct 11 09:37:42 2015 -0400| [f05ff057ff4112bd62dededcc630b1148e079650] | committer: Ganesh Ajjanagadde

configure: fix configure when using gcc

Fixes Ticket4922.

Commit 060102389e572abb2beaed3b9f5e1036aeea43f1 broke configure, since
the inversion ! was missed while converting the grep to a case
statement.
