Thanks for testing that, and it looks like Fedora ran into the same issue: https://github.com/rust-lang/rust/issues/48319

"I think this is from an unfortunate interaction from Fedora using --enable-full-bootstrap for #47469, and some lib-path hacking we're doing to reduce duplication. We currently replace every rustlib/$target/lib/libfoo.so with a symlink to /usr/lib64/libfoo.so. [..]"

We also do a similar thing on Debian, so I think this also applies to us. I'll make sure to disable that option when packaging 1.24. (I'm on holiday atm but I'll try to do it on the 26th or 27th.)
