The build environment is docker snapcraft/xenial-amd64.  I rebuilt the
package from scratch, i.e. in the docker container:

$ cd /path/to/pharo-snap
$ snapcraft clean
$ snapcraft prime

Then on the host (Ubuntu 4.8.0-45.48~16.04.1-generic 4.8.17):

$ sudo snap try /path/to/pharo-snap/prime --classic
$ pharo --version

No, does this mean that 32 bit snap'd applications don't work on 64
bit systems with classic containment?
