Please apply it.

This would be arm-elf only because arm-eabi configurations don't touch the FPA
which is why this didn't show up earlier. My last trawl of this looked for
PRE_DEC and BLKmode - didn't expect an XFmode for this.

arm-unknown-elf fails to build because of an ICE when compiling __

Could someone try this with arm-eabi/elf? That would impact the priority of
this bug.
