Oh yes, there is still work to do in snapcraft for dealing with multiple
target architectures or simple cross-builds. I'd add that we should also
support biarch for folks running 32-bits x86 binaries on x86-64 – I ran in
a case where the same snap would have to run 64-bits and 32-bits utilities.
For now, this can be worked around by running snapcraft on different
architectures natively or in a qemu-system-$arch chroot, but that results
in multiple snaps.

It's all just snapcraft work that needs to get done  :-)

I agree LD_LIBRARY_PATH should be set dynamically for multi-architecture
snaps.

Seems right; perhaps this only has to be done for multi-arch snaps though
