* aout-target.h (callback): Don't define this function if it won't be used.

Browse Source 
* aoutx.h (some_aout_object_p): Restore old aout_data value if this type
doesn't match.  Don't lose if file sections have already been created.
(set_arch_mach): Set reloc_entry_size.
(slurp_symbol_table): Use bfd_h_get_{16,8} for reaeding symbol data.

* hosts/i386bsd.h: New file.
* configure.in: Recognize i[34]86-*-bsd host.

* aout-target.h (callback, write_object_contents): Delete unused variables.

* aoutx.h (reloc_type_lookup): New function.
* aout-target.h (MY_reloc_howto_type_lookup): Use it as default.
* aoutf1.h (sunos4_reloc_type_lookup): Deleted.
(MY_reloc_howto_type_lookup): Don't define it.

* aoutx.h (adjust_sizes_and_vmas): Don't bother with padding for OMAGIC files.
(slurp_symbol_table): Use header byte order, not target byte order, for reading
symbol data.

These numbers make BFD work with that. If your aout 386 system
doesn't work with these, we'll have to split them into different
