+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.

+Do not make symbols hidden on Blackfin
+
+The libselinux logic to hide internal symbols from the DSO doesn't
+work properly on Blackfin due to the USER_LABEL_PREFIX not being
+handled properly. A real fix is not that simple, so this patch simply
+disables the internal symbol hiding mechanism. This means that those
+symbols are visible in the final DSO, which is not a problem for
+proper execution, it just isn't as clean.

+Makefile: revert libsepol: use ln --relative to create .so symlinks
+
+This reverts 71393a181d63c9baae5fe8dcaeb9411d1f253998
+
+ln --relative is too recent to be available in all distributions,
+especially enterprise-grade distros that can stick around as long as
+they are maintained (up to 10 years in some cases?).
+
+For the sake of Buildroot, revert the upstream patch.
