This patch makes sure that the xineplug_decode_ff plugin, that is used by xine
to decode streams using ffmpeg, links against libpostproc and does not rely on
the fact that it's pulled in from other libraries (libavcodec/libavutil).  This
behaviour breaks when using ffmpeg 20060302 or previous with --as-needed
LDFLAGS.

See Gentoo Bug #124802.
