+Add support for static-only build
+
+Instead of unconditionally building shared libraries, this patch
+improves the libsepol build system with a "STATIC" variable, which
+when defined to some non-empty value, will disable the build of shared
+libraries. It allows to support cases where the target architecture
+does not have support for shared libraries.
