When building the kernel with the attached .config settings, the following warning occurs.

attached config: config.tar.gz

WARNING: modpost: EXPORT symbol "rust_build_error" [vmlinux] version generation failed, symbol will not be versioned.
Is "rust_build_error" prototyped in <asm/asm-prototypes.h>?

Thanks for the report! Would you mind attaching it uncompressed (i.e. no tar, no gzip) and/or editing the message to copy-paste the config file as text? That is easier and hopefully helps to search for the issue too.
