of input file, if not specified in input file itself; all callers
updated; `binary_architecture' hack removed.
(copy_archive, copy_file): New parameter `input_arch', for
`copy_object' usage.
(copy_main): Accept `-B' (`--binary-architecture') option also
for any arch-less input ifile format, not only `binary'; remove
bfd_external_binary_architecture hack; instead, add `input_arch'
to calls to `copy_file'.
* windres.c, windmc.c : Obsolete and useless external references
to `bfd_external_binary_architecture' or `bfd_external_machine'
removed.
* binary.c (binary_object_p): Remove bfd_external_binary_architecture
hack. objcopy `-B' (`--binary-architecture') option is now handled
in a generic way.
* dlltool.c (run): Use formatting string to avoid compile time
warning.
(gen_exp_file): Check return value from fread.
* windmc.c (main): Check return value from fread.
