--- Comment #1 from Erhard F. (erhard_f@mailbox.org) ---
Reinvestigated with clang 15 on my PowerMac G5 11,2.
Got further on as kernel + modules are built now. But I get an error at the
linking stage:
# LLVM=1 LLVM_IAS=1 make
CALL scripts/checksyscalls.sh
UPD include/generated/utsversion.h
CC init/version-timestamp.o

Toolchain used was llvm/clang/lld-15.0.3. Same kernel builds fine with
gcc-12.2, binutils-2.39.
