Excellent, can confirm that it works for me, too!
Thanks!!

FWIW the exact commands our build script uses are:
make W=1 LLVM=1 O=build_allmodconfig_cl -j 6 allmodconfig
./scripts/config --file build_allmodconfig_cl/.config -d werror -d kvm_werror -d drm_werror
make W=1 LLVM=1 O=build_allmodconfig_cl -j 6
