[FFmpeg-user] FFmpeg master branch build error for android arm

[Wanghong Lin]

I got linking error when build FFmpeg latest master branch for arm android.

LD ffmpeg_g

libavcodec/libavcodec.so: error: undefined reference to
'ff_put_vc1_chroma_mc8_neon'

libavcodec/libavcodec.so: error: undefined reference to
'ff_avg_vc1_chroma_mc8_neon'

libavcodec/libavcodec.so: error: undefined reference to
'ff_put_vc1_chroma_mc4_neon'

libavcodec/libavcodec.so: error: undefined reference to
'ff_avg_vc1_chroma_mc4_neon'

collect2: error: ld returned 1 exit status

make: *** [ffmpeg_g] Error 1

The same configuration worked fine in FFmpeg 3.0.2

Is it a bug in Makefile? Could somebody fix it?
