Hi, this seems to be causing some problems when generating Xcode project.

When I try to generate the Xcode project with the following command:

  cmake -G "Xcode" -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_OPTIMIZED_TABLEGEN=ON -DLLVM_ENABLE_IDE=ON -DLLVM_CCACHE_BUILD=ON ../../llvm

I get the following error:

> CMake Error in /path/to/llvm-project/clang/lib/Headers/CMakeLists.txt:
>
>   The custom command generating
>   
>     /path/to/llvm-project/build/Xcode-Debug/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)/lib/clang/16/include/larchintrin.h
>   
>   is attached to multiple targets:
>   
>     clang-resource-headers
>     loongarch-resource-headers
>   
>   but none of these is a common dependency of the other(s).  This is not
>   allowed by the Xcode "new build system".
