+        * The compatibility libraries for libsystemd-journal.so,
+          libsystem-id128.so, libsystemd-login.so and
+          libsystemd-daemon.so do not make use of IFUNC
+          anymore. Instead we now build libsystemd.so multiple times
+          under these alternative names. This means that the footprint
+          is drastically increased, but given that these are
+          transitional compatibility libraries this shouldn't matter
+          much. This change has been made necessary to support the ARM
+          platform for these compatibility libraries, as the ARM
+          toolchain isn't really at the same level as the toolchain
+          for other archictures like x86 and does not support
+          IFUNC. Please make sure to use --enable-compat-libs only
+          during a transitional period!
