Sorry, I tried but it was not reproduced. I made the following two changes
to the steps in the 'reproduce' link:
1. Put linux and lkp-tests in two directories of the same level. Because:
   $ git fetch --no-tags linus master
   error: RPC failed; HTTP 403 curl 22 The requested URL returned error: 403
   fatal: error reading section header 'acknowledgments'
2. Compiler was specified by following the prompts.
   COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang-17 ~/lkp-tests/kbuild/make.cross W=1 O=build_dir ARCH=riscv olddefconfig
   COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang-17 ~/lkp-tests/kbuild/make.cross W=1 O=build_dir ARCH=riscv SHELL=/bin/bash
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Image is finally generated, so there should be no problem with the above steps being adjusted:
$ ls build_dir/arch/riscv/boot/
dts  Image  loader  loader.bin  loader.lds  loader.o

By the way, all the symbols to be reported "relocation R_RISCV_PCREL_HI20 out of range" is
generated by the tool kallsyms (scripts/kallsyms.c). So, it seems that the tool kallsyms
have not been executed. And this error is not caused by my patches.
