this should be backported into release-24.05. probably not many rebuilds on that branch as looks like rust just moved to llvm18 on master causing many of the rebuilds

@RossComputerGuy Keep an eye in Hydra builds, to check for downstream, to see if something unusual happens. (When this goes wrong, it can break a lot of things, you know...)
