It looks like there is a new revision of the patch that should resolve
this.

https://lore.kernel.org/r/1646891689-53368-1-git-send-email-lirongqing@baidu.com/

It happens with GCC / GNU as too.

/tmp/cc6grhKv.s: Assembler messages:
/tmp/cc6grhKv.s:52: Error: invalid operands (*UND* and .data sections) for `+'

Cheers,
Nathan
