I'm not sure what's wrong here, but first of all remove:

> --extra-ldflags=-L/home/kirill/FreeScale/rootfs/usr/lib

From your configure lines.  LTIB will automatically find headers/libs 
in these directories.

I think you need to look into the warning:

 In file included from /tmp/ffmpeg-conf-15254-29820-10676.c:1:
> /home/kirill/FreeScale/rootfs/usr/include/x264.h:32:4: warning: #warning
> You must include stdint.h or inttypes.h before x264.h
> check_func x264_encoder_open
> check_ld
> check_cc

And resolve that.
