Yes, it is as I feared. Your patch results in an "arm" package when I do a 
cross-build for "armel" (for which I must of course set ARCH to "arm" as 
armel is not a valid Linux architecture).

I agree that being able to build i386 on amd64 is a valuable option and I 
have actually run into that issue myself (and solved it by building in an 
i386 chroot).

A possible solution could be to check that CROSS_COMPILE is *not* set, but 
I'm not sure if that would be the correct solution. Input from others on 
this would be welcome.
