It's actually what os_arch uses internally, but it filters x86_64 and
translates it to i386:

  switch -exact -- $::tcl_platform(machine) {
      x86_64 -
      i686 -
      i586 {
          return i386
      }
      {Power Macintosh} {
          return powerpc
      }
  }

Apparently it might also contain i586, i686 depending on your system.
You should handle this case, too.
