Ah, you're looking at mereswine, which is hard-float according to

checking build system type... armv7l-unknown-linux-gnueabihf
checking host system type... armv7l-unknown-linux-gnueabihf

I also confirmed that our existing code works on Fedora 30 armv7l
(also hard-float) with gcc 9.3.1. That's the only other ARM32
image I have at hand :-(

So yeah, it would seem they broke it between 10.2.1 and 10.5.0.
