That hasn't been the full story for a while. FPA (the obsolete,
usually emulated floating point format) does this, but all modern
systems use VFP word ordering, even if they have only software
floating point.
I don't see a single clear macro that determines this. __VFP_FP__ is
a subset of the times that normal IEEE layout is used.
