-Subject: [PATCH] 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.
