+Subject: [PATCH 3/3] libtool: Enable shared library support for SerenityOS
+
+For some odd reason, libtool handles the configuration for shared
+libraries entirely statically and in its configure script. If no
+shared library support is "present", building shared libraries is
+disabled entirely.
+
+Fix that by just adding the appropriate configuration options for
+`serenity`. This allows us to finally create dynamic libraries
+automatically using libtool, without having to manually link the
+static library into a shared library.
