libsepol1 binary package in Ubuntu Xenial s390x

 Security-enhanced Linux is a patch of the Linux kernel and a number
 of utilities with enhanced security functionality designed to add
 mandatory access controls to Linux. The Security-enhanced Linux
 kernel contains new architectural components originally developed to
 improve the security of the Flask operating system. These
 architectural components provide general support for the enforcement
 of many kinds of mandatory access control policies, including those
 based on the concepts of Type Enforcement®, Role-based Access
 Control, and Multi-level Security.
 .
 libsepol provides an API for the manipulation of SELinux binary policies.
 It is used by checkpolicy (the policy compiler) and similar tools, as well
 as by programs like load_policy that need to perform specific transformations
 on binary policies such as customizing policy boolean settings.
