+Makefile: revert libselinux: 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.
