rust build failure on Fedora 41

One error out of 18756. Is the rust compiler still useable? I just installed it for the first time. I'm trying to compile resvg.

I never ran the UI tests via x. We have our own tool in this repo to run the UI tests and there are quite a few that still fail as of this day, so that seems normal to me.

Were you able to successfully compile resvg and have all of its tests to pass with rustc_codegen_gcc?
