Dank QEMU lassen sich mit sbuild sogar Pakete fuer voellig andere Architekturen bauen.
Dazu muss man zunaechst erstmal QEMU installieren:

Danach erzeugt man den chroot fuer die gewuenschte Architektur mit Hilfe der --foreign-Option, z.B. fuer armhf (Architektur des Raspberry Pi 2):

Dann kopiert man die statisch-gelinkte QEMU-Binary fuer ARM einfach in den chroot und ruft danach ./debootstrap/debootstrap --second-stage auf, nachdem man mit chroot wieder in den chroot gewechselt ist:
root@vs76:/local_scratch> cd sid-armhf-sbuild/ root@vs76:/local_scratch/sid-armhf-sbuild> cp -av /usr/bin/qemu-arm-static usr/bin ‘/usr/bin/qemu-arm-static’ -> ‘usr/bin/qemu-arm-static’ root@vs76:/local_scratch/sid-armhf-sbuild> chroot . bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) I have no name!@vs76:/# ./debootstrap/debootstrap --second-stage I: Keyring file not available at /usr/share/keyrings/debian-archive-keyring.gpg; switching to https mirror https://mirrors.kernel.org/debian I: Installing core packages...

Dann einfach wie oben beschrieben eine schroot-Konfiguration fuer sid-armhf-build anlegen und dann beim Bauen mit sbuild einfach noch --arch=armhf mit angeben.
Fertig.
