hmm. I still cannot reproduce this. Here is my command:
```
cmake \
    -G Ninja \
    -DCMAKE_ASM_COMPILER=$MYCLANG \
    -DCMAKE_ASM_COMPILER_ID=Clang \
    -DCMAKE_BUILD_TYPE=Debug \
    -DCMAKE_CXX_COMPILER=$MYCLANG++ \
    -DCMAKE_C_COMPILER=$MYCLANG \
    -DLLVM_TARGETS_TO_BUILD="X86;AArch64" \
    -DLLVM_DEFAULT_TARGET_TRIPLE=x86_64-redhat-linux-gnu \
    -DLLVM_ENABLE_ASSERTIONS=ON \
    -DLLVM_ENABLE_LLD=ON \
    -DLLVM_ENABLE_PROJECTS="clang;lld;bolt" \
    -DCMAKE_EXE_LINKER_FLAGS="-L /usr/lib64" \
    -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON \
    ../llvm

     ninja check-all
```
Is something else missing?
