binutils 2.43 has stricter validation for labels[1] and results in errors
when building ffmpeg for armv5:
src/libavcodec/arm/mlpdsp_armv5te.S:232: Error: junk at end of line, first unrecognized character is `0'
Remove the leading zero in the "01" label to resolve this error.

The snow encoder uses block based motion estimation which can read out of array if
insufficient alignment is used
It may be better to only apply this for the encoder, as it would safe a few bytes of memory
for the decoder. Until then, this fixes the issue in a simple way.
