nodejs 26.8.2 fails to build with clang/LLVM

Version

26.8.2

Platform

Linux (Gentoo with LLVM profile)

Subsystem

LIEF (or forzen)

What steps will reproduce the bug?

1. Build nodejs version 26.8.2 with clang
2. Observe failure

How often does it reproduce? Is there a required condition?

Always while building with clang

What is the expected behavior? Why is that the expected behavior?

Successful build with clang

What do you see instead?

Build failure while building with Clang

Additional information

I think this is due to stricter include requirements on clang
I was able to build by adding #include <functional> in deps/LIEF/third-party/frozen/include/frozen/map.h

从 deps/LIEF/third-party/frozen/include/frozen/map.h 开始，然后使用 Clang 在 Linux 上复现 Node.js 26.8.2 的构建。检查错误中报告的标准库依赖项，并验证使用 Clang 的构建能够成功完成，且不会出现 std::less 未定义错误。
