setarch: provide backwards compatibility
The getopt_long(3) use introduced by commit
8df90dec2bfd8c876ddd4cea010f40550d4e24aa
broke backwards compatibility.
Old behavior:
$ i386 uname -m
i686
New behavior:
$ i386 uname -m
i386: invalid option -- m
Linux
Traditional method to fix it is to disable program arguments reordering
by prefixing getopt_long's optstring with '+' character.
