我已经成功编译了3.6.1版本的LLVM-Clang-LLDB-Compiler-RT-LibCxx-LibCxxABI-TestSuite软件包。但是，当我尝试ninja check-all时，检查在第一个目标[1/150] Generating sanitizer_bitvector_test.cc.x86_64.o处失败。我认为原因是LLVM正在尝试使用系统GCC头文件，但我使用另一个GCC工具链（GCC 4.8.4）编译了LLVM，我将其编译并安装在非根目录中。但是，我无法弄清楚如何让CMake避免使用系统GCC头文件（我修改了PATH和LD_LIBRARY_PATH，但它们根本没有帮助。）
以下是相关信息：

ninja check结果没问题，这意味着LLVM已成功编译：

特别是你可能会注意到： /usr/lib/gcc/x86_64-redhat-linux/4.4.7 /../../../../ include / c ++ / 4.4.7 被使用。但是，'ninja check-all'确实应该使用gcc-4.8.4的头文件，而不是gcc-4.4.7（系统捆绑的gcc）。
我已经提交了一份错误报告，但似乎没有人愿意接听。
如果有人知道如何解决这个问题，请告诉我。感谢。
