In the process of reorganizing the code, mkarchroot was split into two
binaries with complementing functionality.

arch-nspawn is a thin wrapper around systemd-nspawn, doing some
pacman-specific stuff like copying config from the host and binding
the cache.

mkarchroot (which now just builds the chroot instead of also providing
chrooting functionality) makes use of arch-nspawn, as do makechrootpkg
and archbuild.
