[orca-list] Accessibly running 32-bit apps on AMD64

[Nolan Darilek <nolan thewordnerd info>]

   I swear I saw this answered somewhere recently, but I can't find it 
when I need it.

I'm trying to run the 32-bit pre-built Thunderbird binaries on an AMD64 
system--Ubuntu, to be exact. There isn't a pre-built package for the 
version I want, so the daily PPA isn't an option. While TB launches 
fine, it fails to launch accessibly.

Launching in the console, I see lots of errors with libraries, but 
notably I see roughly this, which I'm loosely transcribing as I don't 
have working email on the affected box:

Failed to load module atk-bridge: wrong ELF class: ELFCLASS64

Like I said, despite these errors, the app seems to load and work OK, 
just without accessibility. And it can clearly find the module, but I'm 
guessing there's an issue with the fact that my modules are 64-bit and 
the app isn't.

Is there a way to get pre-compiled apps for 32-bit architectures working 
with Orca? Or is my only option to rebuild?

Thanks.
