Thanks for your insight, Dimitri; it prompted me to rethink things, and 
instead I have managed to fix the project I was attempting to compile to 
not attempt to install the g++-multilib package on those architectures. 
This fixes my build on the launchpad buildd - I'm building snap packages 
which were failing to build for those architectures because of trying to 
install g++-multilib. Specifically it's the "snapcraft-preload" [1] 
project by Sergio (sergiusens) that was breaking things for me :-)

I've filed a PR to the snapcraft-preload project now on github [2]

Thanks,
Dan.
