[FFmpeg-devel] [PATCH] configure: force erroring out in check_disable_warning() if an option doesn't exists

[James Almer]

Should prevent some options from being added to cflags when they
don't exist and the compiler only warns about it.

I figure this is safer than adding
-Werror=unused-command-line-argument -Werror=unknown-warning-option
as Ronald suggested.
