Currently, it unsets ARCH, so it uses the build architecture. This is
fine if you have the full kernel sources, which is usually the case.
However, an install-extmod-build script was added to Linux fairly
recently that installs just the files needed to build out-of-tree
modules in a distro-neutral manner. It saves space by only including the
arch files for the target architecture.

I checked the history, and tc-arch-kernel didn't exist when the unset
line was added. If it had, this approach probably would have been taken
at the time.
