I would like to implement this in Fedora, but jpackage-utils is not
mulitlib-aware.  Given that jpackage-utils installs directories in /usr/lib, it
would make sense to make it architecture-specific.  Currently, we use the
simpler approach of hard-coding _libdir to /usr/lib64 in the spec files of
64-bit JDKs and appending .%{_arch} to their JAVA_HOME directories.  I haven't
done much research into making jpackage-utils multilib (i.e., checked how Debian
and Gentoo handle this), but at some point we should probably go back and design
jpackage-utils/multilib interaction more thoroughly.
