Currently GNU make already removes files when catching an interruption signal, however, in order to deal with other kinds of errors a workaround is in place to store target output to a temporary file, and only move it to its right place on success. By enabling the built-in .DELETE_ON_ERROR we let make do this task, so we don't have to. This way the rules can be simplified a lot.
