Ok, so it's not too badly broken. Good.

Also, while it's been a long time since we needed FPU emulation on the
i486sx, I don't recall the details of any of the (much more modern)
IoT small cores. I *think* the base platforms are all at a Pentium
level (ie not just FPU, but MMX), but maybe there's some reason to
keep FP emulation alive for some platforms.
