I would observe here that this probably works for ipk and multilib and
only breaks for multilib+rpm. The reason is that rpm collapses the
namespace when it creates the package list so "lib32-bash" becomes bash.
I think this might be an error in however we generate the INSTALLED_PKGS
list and we might need to revisit the rpm mechanism and ensure the
multilib prefixes get added.
