Linux ZMAGIC support from Eric Youngdale <ericy@cais.cais.com>.

Browse Source 
* libaout.h (struct aoutdata): Add field zmagic_disk_block_size.
	* aout-target.h (MY(callback)): Only set alignment according to
	architecture if the section sizes are aligned to that alignment,
	for backward compatibility.
	(MY(set_sizes)): Initialize zmagic_disk_block_size field.
	* aoutx.h (adjust_z_magic): Set ztih if using q_magic_format.  Set
	text section filepos to zmagic_disk_block_size if not ztih.  Use a
	different padding algorithm if not ztih.
	* i386linux.c (MY_text_includes_header): Don't define.
