<pre>
    I'm very new to cmake and only know failure.
By running that
```
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
git checkout llvmorg-16.0.2
mkdir build
cd build
echo Note at this point, you have to remove "-fuse-ld=\${LLVM_USE_LINKER}" in llvm-project/llvm/cmake/modules/HandleLLVMOptions.cmake
echo Use Ctrl-F to find it and remove the entire if statement
pause
CC='clang' CXX='clang++' cmake -G Ninja -DCMAKE_C_FLAGS="-flto -Oz" \
-DCMAKE_CXX_FLAGS="-flto -Oz" \
-DCMAKE_ASM_FLAGS="-flto -no-integrated-as" \

-DLLVM_EXTERNAL_PROJECTS="clang;lld" \

-DLLVM_ENABLE_PIC=False ../llvm
ninja
```
At the end I get:
```
[241/3656] Linking CXX executable bin/llvm-tblgen
FAILED: bin/llvm-tblgen 
: && /usr/local/bin/ld.lld && :
ld.lld: error: no input files
[243/3656] Building CXX object lib/Option/CMakeFiles/LLVMOption.dir/Arg.cpp.o
ninja: build stopped: subcommand failed.
```

Also, what I want is:
- Compile newer clang with older clang
- Newer clang runs on x86_64
- Newer clang targets either x86_64 (by default) or ARM
Tell me if the flags are wrong.
