Emacs is always dumped with a few buffers, because temacs needs them
to do the dumping.  See this comment text from buffer.c:

	 Implementation notes: the buffers we carry from temacs are:
	 " prin1", "*scratch*", " *Minibuf-0*", "*Messages*", and
	 " *code-conversion-work*".  They are created by
	 init_buffer_once and init_window_once (which are not called
	 in the dumped Emacs), and by the first call to coding.c
	 routines.
