Can you explain the nature of the breakage? It's probably also easy to
fix (or was already arguably broken), but it would be helpful if you'd
point at what you think is wrong rather than making me guess.

That doesn't seem unreasonable. After all, if the .config values are no
longer being forcibly overridden to match the build host, you no longer
*need* to add ARCH=i386 on the command line just to make the build
system honour your existing configuration with CONFIG_64BIT=n. So
there's absolutely no point in having ARCH=i386 there. If you want the
more stringent checks, don't do that then. But I'll take a look at this
too. Thanks for actually giving enough detail.
