   cc can't currently be updated due to a build problem with riscv. More info at #65445 (comment). I think the issue is that rustbuild uses cc to discover cc toolchains, and cc-rs gained riscv support, and so now it thinks it should use a gcc toolchain that doesn't exist. The detection is in https://github.com/rust-lang/rust/blob/master/src/bootstrap/cc_detect.rs and Alex mentioned just setting a CC_* env var in the riscv container might be enough. It's been on my todo list for a while, but I haven't had a chance to look at it. I can maybe try to look at it this weekend.
