Is this like the 32-bit Freescale things with the weird alternate FPU?
We support those for ppc32 as soft-float (and AIUI the ABI for use
with the FPU matches soft-float ABI, so in theory it could be
supported but we were never clear on whether it's IEEE-conforming) but
I wasn't aware of anything like that for 64-bit so it was never added.
Assuming it's the same concept, I don't see a reason we couldn't add
