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