[OE-core] can't compile ffmpeg without x11

[Yi Qingliang]

HELLO!

in ffmpeg.bb:

DEPENDS = "alsa-lib zlib libogg yasm-native libxv"
PACKAGECONFIG ??= "... ${@bb.utils.contains('DISTRO_FEATURES', 'x11',
'x11', '', d)}"


the 'DEPENDS' says it need libxv which need x11, so the x11 detection
in 'PACKAGECONFIG' will not work anymore.

can I use ffmpeg without x11 ? (indeed, I want to use opencv)

the old poky will work with libav, but now libav has been dropped.
