Subject: [PATCH 3/3] f2fs-tools:sload.f2fs compress: Fixed automake

From: Robin Hsu <robinhsu@...gle.com>

Fixed automake for sload.f2fs compression support

./configure now will by default depends on liblzo2 and liblz4.

To compile without liblzo2 (and thus not support liblzo2 compression),
run ./configure with '--without-lzo2' option.

To compile without liblz4 (and thus not support liblz4 compression),
run ./configure with '--without-lz4' option.
