Re: [OE-core] [PATCH] rust: Disable 64bit atomics on crossbeam on riscv32

[Alexander Kanavin <alex.kanavin@gmail.com>]

We carry this patch, so that manual per-target fixups like this are
not needed, and crossbeam's internal lists are used properly:

https://git.yoctoproject.org/poky/tree/meta/recipes-devtools/rust/rust/crossbeam_atomic.patch?h=master-next&id=f4fe7cdaa7fc5785c55bd507c897f4d25d43cffa

Is it not working somehow? Does the list itself need to be fixed?
