I have get_scratch_packages.sh that can be used to verify multilib
conflicts for people with monoarch platforms. It requires
multilib-cmp.py that somebody else wrote, I attach it, maybe not the
latest version, though.

# Simple script to help ferret out multilib conflicts.
#
# Can be used in two different modes.  The first is comparing two
# packages given on the command line and showing any conflicts.
#    multilib-cmp.py <pkg1> <pkg2>
# Can also be used to find multilib conflicts in a tree
#    multilib-cmp.py <tree>
