Without patch:
arm-linux-androideabi/bin/ld: libavcodec/libavcodec.so: error: undefined 
reference to 'ff_fft_fixed_calc_neon'
arm-linux-androideabi/bin/ld: libavcodec/libavcodec.so: error: undefined 
reference to 'ff_fft_permute_neon'
arm-linux-androideabi/bin/ld: libavcodec/libavcodec.so: error: undefined 
reference to 'ff_fft_calc_neon'
collect2: ld returned 1 exit status
make: *** [ffprobe_g] Error 1

With patch compiles correctly.
