Based off the debian bug report this is fixed in at least Ubuntu 16.04. I tested this with Ubuntu 19.04 and can confirm it is fixed in that version as I was able to create an armhf chroot. After running mk-sbuild I received the following message:
Done building snapper-armhf.
To CHANGE the golden image: sudo schroot -c source:snapper-armhf -u root
To ENTER an image snapshot: schroot -c snapper-armhf
To BUILD within a snapshot: sbuild -A -d snapper-armhf PACKAGE*.dsc
To BUILD for : sbuild -A -d snapper-armhf --host PACKAGE*.dsc
