Rust toolchain has already a bug since 2015: it cannot link statically libgcc, namely it does not have "-static-libgcc" option since 2015.
I got the bug with "TinyGlade" video game (extremely good BTW), which is written in rust, and with the dev we hit that bug. Namely... better have a libgcc with the right ABI... and I can tell you, this has a been a HUGE issue since valve started to distribute games more than a decade ago.
As in you have to build on an old distro? Or something else?
