在按照https://github.com/mollybuild/RISCV-Measurement/blob/master/Build-RISCV-LLVM-and-run-testsuite.md执行测试任务时报错。

测试源码：https://github.com/plctlab/llvm-project.git
测试分支：origin/rvv-iscas
commit id：c360b611314ec39777487d050af6daa24eae811c

测试步骤：

$ git clone https://github.com/plctlab/llvm-project.git

$ cd llvm-project

$ mkdir build && cd build

$ cmake -DLLVM_PARALLEL_LINK_JOBS=3 -DLLVM_TARGETS_TO_BUILD="X86;RISCV" -DLLVM_ENABLE_PROJECTS="clang" -G Ninja ../llvm

$ ninja

$ ninja check

在执行ninja check的时候，出现以下错误：
