我不使用 TBB，但我收到与 TBB 相关的链接器错误

问：

我有一些测试代码，其中包括：

#include <stddef.h>
#include <stdio.h>
#include <algorithm>
#include <chrono>
#include <execution>
#include <random>
#include <ratio>
#include <vector>

当我使用 Clang/Linux 构建它时，我收到这些链接器错误，这似乎意味着我正在使用 TBB 库（我不是）：

如果我注释掉这一行代码：

sort(std::execution::par_unseq, sorted.begin(), sorted.end());

程序生成成功。

这是怎么回事？clang 在下面使用 TBB 吗？
