I meant an order of posts in this particular thread ;)

Looking at t-rtems file it's obvious you indeed tried rather hard.

I definitely agree with you that current state of PPC BSPs as a whole is total
mess. I myself dislike quite a few decisions made in the new exception
processing, but for the sake of clarity, I'd just remove all the BSPs that
don't support new exception processing from multilib variants. If somebody
(like me) wants to use them, he can build a tool-chain with customized
t-rtems. Besides, if I remember correctly, that's what Joel said will
be done when switching to multilib has been considered.
