I can confirm that this also occurs in bcachefs-tools-1.9.0

Looks like a Gentoo issue I faced a while ago. Could you try creating /etc/portage/env/sys-fs/bcachefs-tools with the following contents:

RUSTFLAGS="${RUSTFLAGS} -Clink-arg=-lgcc"

I think the issue is that rustc passes -nodefaultlibs to the linker (clang+lld) which means "libgcc" (or in clangs case compiler-rt) containing the __cpu_model isn't part of the final linker call.

Thank you I have passed -C default-linker-libraries, which I believe disables -nodefaultlibs. This makes it compile on my system. Since my system is incompatible with gcc, I wouldn't be able to use -lgcc, unless if I am misunderstanding what that flag does. I don't think -lcompiler-rt is a valid flag.

Afaik clang resolves -lgcc to whatever it was configured with at build time. You can check this via clang --print-libgcc-file-name which should return some kind of libclang_rt.builtins-*.a

EDIT: well not build time but what is set as the default --rtlib in /etc/clang

Ah I see now is there a way to specify that directly? And second of all does using -C default-linker-libraries achieve the same result?

If you want to override the default from /etc/clang just pass the flag again e.g. clang --rtlib=compiler-rt

And second of all does using -C default-linker-libraries achieve the same result?

Not too sure there but I think it should be about the same
