@mgorny, I have updated the patch according to the suggestions from @tstellar in https://reviews.llvm.org/D141581#4069857.

I have used the script below to test the stand-alone build of clang. Indeed, the error related to the cmake configuration for RISCVTargetParserDefs has disappeared. However, there is an (unreltaed) error that does not allow me to test the full build:

  CMake Error at /Users/fpetrogalli/projects/cpu-defs/install/lib/cmake/llvm/LLVMExports.cmake:1222 (set_target_properties):
    The link interface of target "LLVMLineEditor" contains:
  
      LibEdit::LibEdit
  
    but the target was not found.  Possible reasons include:
  
      * There is a typo in the target name.
      * A find_package call is missing for an IMPORTED target.
      * An ALIAS target is missing.
  
  Call Stack (most recent call first):
    /Users/fpetrogalli/projects/cpu-defs/install/lib/cmake/llvm/LLVMConfig.cmake:329 (include)
    CMakeLists.txt:38 (find_package)

Script used for testing:

  % cat standalone.sh
  #!/bin/sh
  
  build_llvm=`pwd`/build-llvm
  build_clang=`pwd`/build-clang
  installprefix=`pwd`/install
  llvm=`pwd`/llvm-project
  mkdir -p $build_llvm
  mkdir -p $installprefix
  
  cmake -G Ninja -S $llvm/llvm -B $build_llvm \
        -DLLVM_INSTALL_UTILS=ON \
        -DCMAKE_INSTALL_PREFIX=$installprefix \
        -DCMAKE_BUILD_TYPE=Release
  
  ninja -C $build_llvm install
  
  cmake -G Ninja -S $llvm/clang -B $build_clang \
        -DLLVM_EXTERNAL_LIT=$build_llvm/utils/lit \
