Not if you had a /usr/lib32 -> /emul/ia32-libs/usr/lib link when
/usr/lib32/libutil.a was installed. The file would end up in emul
while dpkg only knows it under /usr/lib32.

You installed a package with /usr/lib32/foo while /usr/lib32 was still
a link. Then you upgraded libc6-i386 which removed that link and
replaced it with a directory. Last when dpkg wanted to remove
/usr/lib32/foo on upgrade it was already gone and nothing was removed.
/emul/ia32-linux/usr/lib/foo remains behind.
Cruft in /emul/ia32-linux/ is what one would expect from updates from
the broken libc6-i386 to a more recent one. Since it only affects a
minority of unstable users the maintainer felt it was ok to leave them
with the pieces (i.e. clean up /emul yourself).
