0.182+20210203-1.1 doesn't seem to solve this as intended, and triggers
a similar failure mode on a more frequently co-installed pair of
architectures:

$ apt-get download libelf1 libelf1:i386
$ aunpack libelf1_0.182+20210203-1.1_amd64.deb
$ aunpack libelf1_0.182+20210203-1.1_i386.deb
$ diff -ru libelf1_0.182+20210203-1.1_*/usr/share/
Binary files libelf1_0.182+20210203-1.1_amd64/usr/share/locale/en@boldquot/LC_MESSAGES/elfutils.mo and libelf1_0.182+20210203-1.1_i386/usr/share/locale/en@boldquot/LC_MESSAGES/elfutils.mo differ
