+- Update to 21.3.4:
+- Changes for 21.3.4:
+ * http://erlang.org/download/OTP-21.3.4.README
+ * crypto: Fixed build link error on Windows. Unresolved symbol
+   'bcmp'.
+ * erl_interface: Fix handling of Makefile dependencies so that parallel
+   make works properly.
+ * erts: Fix erlang:open_port/2 with the fd option to correctly
+   cleanup the pollset when the port is closed. Before
+   this fix there would be error printouts sent to logger
+   when the same fd was reused in a new port.
+ * ssh: The callback ssh_channel:init/1 was missing in OTP-21
+ * ssh: If a client was connected to an server on an already
+   open socket, the callback fun(PeerName,FingerPrint) in
+   the accept_callback option passed the local name in the
+   argument PeerName instead of the remote name.
+ * common_test: OTP internal test improvements.
