smack: new package.

SMACK stands for Simplified Mandatory Access Control Kernel. It is a Linux
Security Module which provides a Mandatory Access Control mechanism,
like SELinux, but aiming towards simplicity.

This package provides the tools to load/unload the policy from the
kernel as well as a library allowing applications to interact with
SMACK. The proper kernel options are also set.

[Thomas:
- fixed license to be LGPLv2.1 instead of LGPLv2.1+. Even though the
  debian/copyright file has the "or later" indication, none of the .c
  source files carry it, so I suppose LGPLv2.1 is more correct.
- added !BR2_PREFER_STATIC_LIB dependency.
- added dependency on host-pkgconf, since Smack configure.ac uses
  PKG_CHECK_MODULES.]

+	  SMACK stands for Simplified Mandatory Access Control Kernel.
+	  It is a Linux Security Module which provides a Mandatory Access
+	  Control mechanism, aimed towards simplicity.
+
+	  This package provides a library which allows applications to work
+	  with SMACK and tools to load/unload rules from the kernel, as well
+	  as query the policy.
+
+	  SMACK requires the following kernel options to be enabled:
+
+	  - CONFIG_SECURITY
+	  - CONFIG_SECURITY_SMACK
+	  - CONFIG_SECURITY_NETWORK
+
+	  These options will be automatically enabled by Buildroot if it is
+	  responsible for building the kernel. Otherwise, if you are building
+	  your kernel outside of Buildroot, make sure these options are
+	  enabled.
+
+	  To activate SMACK, do not forget to add "security=smack" to your
+	  kernel command line.
