For this package its easy to fix because all data files are arch specfic. 

If we decide to fix some other fedora packages(normally input method db, game
data, voice db and etc.), it'll be very complicated.

e.g.
espeak http://koji.fedoraproject.org/koji/rpminfo?rpmID=1829417

It contain both noarch files and endian-specfic data files, the default install
path for those files are {_datadir}/%{name}-data. The source code defines a
macro for its datadir, if we simply cheat dadadir macro to {_libdir}, then we
need to install all other noarch files to %{_libdir} too. Also according to
FHS, lib64 is designed for 64bit libraries, it seems more reasonable to install
those data files to /usr/lib instead of %{_libdir}.
