No, the package is perfectly fine:

$ apt-cache  policy liblz4-tool liblz4-1

Maybe that weird script is broken.

Title:
  liblz4-tool packaging

Status in lz4 package in Ubuntu:
  Invalid

Bug description:
  I have Lubuntu 16.04 which uses lubuntu-desktop.  That pseudo-package includes liblz4-1 (= 0.0~r131-2ubuntu2).
  I am now trying to install iRedMail_0.9.6 by means of its bash script, which calls for liblz4-tool to be installed. 
  But instead of having the dependency liblz4-1 (= 0.0~r131-2ubuntu2) liblz4-tool wants liblz4-1 (= 0.0~r131-2) and can't match it.
