* 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.
