[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=86dcd0e6fecf0d19ceee211e0efc586aa023cb31
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Sepolgen is currently a host-only package, however it is a dependency
of audit2allow.  This patch allows for sepolgen to be compiled for the
target.

[Thomas:
 - fix formatting of Config.in file
 - add missing dependencies inherited from the fact that the package
   selects python3.]

+	  This package contains a Python module that forms the core of
+	  the modern audit2allow (which is a part of the package
+	  policycoreutils).  It contains infrastructure for parsing
+	  SELinux related messages as produced by the audit system.
+	  It has facilities for generating policy based on required
+	  access.
