LZ4 has been updated with LZ4 Streaming Format specification(v1.3).
lz4demo is replaced by lz4c. lz4c supports both the new streaming and
legacy format with -l option.

This patch makes use of lz4c to support legacy format which is
used for LZ4 De/compression in the linux kernel.

You probably want to check for the presence of lz4c on the system and
bail with an informative message if absent.
