You can use QEMU for that. I use qemu-user in Debian to create a
complete build environment for emulator-based cross-building [1].

You basically create a chroot for the target, copy the qemu-user
binary for the target architecture into it and then just configure
sbuild to use it.

Note: If you create the chroot for armhf, you must not use the
      debian-ports mirror but the regular mirror:

> debootstrap --variant=buildd --foreign --arch=armhf unstable sid-armhf-sbuild http://ftp.debian.org/debian/

And you don't need to overwrite the etc/apt/sources.list in the
case of armhf.

Let me know if you need anymore help.
