Description of problem:
I see that neither ibus-gtk nor gtk2-immodule* are multilib in F11.
Is this the right place to report that? :)

Steps to Reproduce:
1. try to install ibus-gtk or gtk2-immodule* multilib
2. install into x86_64 from i386 repo
3. update gtk2 version
  
Actual results:
1. not available
3. fails because broken deps from 2

Expected results:
gtk immodules needs need to be multilib.

Additional info:
I think

            if fnmatch(dirname, '/usr/lib*/gtk-2.0/*/immodules'):

needs to be added to mash/multilib.py
