* coff-mips.c (ecoff_mkobject_hook): Mark ZMAGIC files as D_PAGED.

	* coff-mips.c (ecoff_mkobject_hook): Mark ZMAGIC files as D_PAGED.
	(ecoff_write_object_contents): If not D_PAGED, don't add the
	section headers to text_size.  If not D_PAGED, set the magic
	number to OMAGIC rather than ZMAGIC.  If creating a D_PAGED
	executable, the executable must fully occupy an even number of
	pages.
	(ecoff_set_symbol_info, make_bfd_asection, ecoff_little_vec,
	ecoff_big_vec): Consistently set section alignment power to 4,
	since ECOFF sections should be multiples of 16 bytes.
	(ecoff_little_vec, ecoff_big_vec): Added D_PAGED to object_flags.
	Made ar_pad_char and ar_max_namelen agree for both.
