Comment # 6 on bug 3953 from Nicolas Chauvet

You should use:
%global        debug_package %{nil}
%global        __strip /bin/true
To avoid packaging issues with pre-built applications.

Use: ExclusiveArch:  x86_64 i686

It's usually better to use one BR per line for better readability with patches
when one or another is removed.

There are lot of comment in the spec files, please clean them.
