You should be able to reproduce this issue as long as you hit a NOTYPE
symbol as the second entry. Using aarch64 and CFI_CLANG will make this
scenario more likely to happen. I believe I used the following:

  $ make LLVM=1 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig
  $ ./scripts/config -e CFI_CLANG
  ...
