Need the i686 rpms for plugins in the x86_64 repo

[Alejandro Alvarez Ayllon]

Hello,

A couple of packages I [co-]maintain are heavily plugin-based, and those 
plugins are installed under /usr/lib(64)/<project name>/, while the core 
libraries are installed into /usr/lib(64)

Then, there are other projects that have their own set of libraries, 
depend on the core libraries, and also require a subset of the plugins 
to provide a basic functionality.

So, at the end of the day, in the epel6 x86_64 repo I have the i686 rpms 
for the dependent project and the core libraries, but only the x86_64 
plugins, so the 32 bits version is basically uninstallable.

I am guessing that the i686 rpms are copied when there is a .so 
installed under %{_libdir}. Is there any way I can trigger the rpms 
containing the plugins to be copied as well?

Best regards,
Alejandro Álvarez
