It does work on the "armv7" target BF animals, though.  I assume they
don't get any updates as they're all old/defunct distros (one of my
favourite features of our boneyard^Wbuildfarm), but one of them is GCC
"10.2.1 20210110", which is what made me suspicious of that -mfpu
stuff, beyond my comprehension without a lot more coffee, that got
backpatched in late 2021.
