I think it is unrelated.


The 0-day bot has already shown the real reason
of the error:

   clang --target=3Driscv64-linux-gnu -no-integrated-as
--prefix=3Driscv64-linux-gnu- -Werror=3Dunknown-warning-option: unknown
assembler invoked
   scripts/Kconfig.include:50: Sorry, this assembler is not supported.


This happens when the proper toolchains are not found.

That is, make.cross passed CROSS_COMPILE=3Driscv64-linux-gnu-
to the make command line, but riscv64-linux-gnu binutils
are not installed on the system.


Without installing binutils-riscv64-linux-gnu,
I can see a similar error log.

It can be fixed by installing riscv64-linux-gnu toolchains.

On debian or its variants,

you can do it by
"sudo apt install binutils-riscv64-linux-gnu"


Or, you can download it from
https://download.01.org/0day-ci/cross-package/gcc-11.2.0-nolibc/


Then, the 0day bot command will proceed.
