I'd like to simply install small endian-specfic data into %{_datadir}, but
without noarch for those package. For big endian-specific data, I suggest to
split them into two noarch subpackages.

Tweak spec is much more eaiser than patching software to use arch-independent
endian files or utilize endian-specfic data in %{_libdir}.

History show many packages install their endian-specfic data into %{_datadir},
but few packages install those data into %{_libdir} as I known.

e.g.
gcin: Input method for Traditional Chinese
scim-fcitx: FCITX Input Method Engine for SCIM
espeak: Software speech synthesizer (text-to-speech)

Notes:
Their are also some disscussion on debian's mail list. 
For espeak, the final decision is simply revoking noarch for espeak-data.
See http://packages.debian.org/sid/espeak-data

For sunpinyin(big data), the final decision is split endian-specfic data into
two noarch subpackages.

If we decide to treak endian-specfic as arch-specfic, then a lot of packages in
repo need patching. Also, it may waste space for end users, if we considring
multilib circumstance. For F13, all primary arch is little endian now,
splitting big endian-specfic data into noarch subpackage will also save space
in fedora mirrors.
