* configure.in (AC_C_BIGENDIAN): Invoke.
* configure: Regenerate.
* write.c (write_object_file <!BFD_ASSEMBLER>): Don't use sizeof
host variable to set string header size.
* config/obj-aout.c (obj_header_append): Don't use host structs.
(obj_symbol_to_chars): Likewise.
(obj_emit_strings): Likewise. Use the passed in output pointer.
* config/obj-aout.h (H_GET_FILE_SIZE): Include H_GET_LINENO_SIZE.
* config/obj-bout.c (obj_emit_relocations): Use md_reloc_size,
not sizeof host struct.
(obj_header_append, obj_symbol_to_chars): Don't use host structs.
(obj_emit_strings): Likewise.
* config/obj-bout.h (EXEC_BYTES_SIZE): Define.
(N_TXTOFF, H_GET_FILE_SIZE, H_GET_HEADER_SIZE): Use instead of
sizeof host struct.
(H_SET_SYMBOL_TABLE_SIZE): Hard code sym size rather than using
sizeof host struct.
(host_number_to_chars): Define.
* config/obj-hp300.c (hp300_header_append): Don't use sizeof
host internal struct to set header sizes.
* config/tc-i960.c (md_number_to_field): Warning fix.
(md_ri_to_chars): Use host byte order.
(get_cdisp, md_apply_fix3): Warning fix.
