[csw-maintainers] opening both 32bit and 64bit shared libs

[Darin Perusich]

Hi Dago,

I see what you're saying but the behavior I'm seeing is that it's only
attempting to open the 64bit lib and never the 32bit one, see below.
I've been in contact with the Amanda developers and they're not sure
what's going on or how to proceed. From how things appear the problem is
outside of the amanda libs and is glib2 related.

I've definitely reached a point where I don't know how to proceed so any
guidance will be greatly appreciated.

Thanks
