ios 无法构建

分支: 0.4.4
环境: Apple M2 14.6.1 xcode 15.4

（arm64）
./build_external.sh iOS

在build_curl 过程中出现一下问题

出现：clang: error: linker command failed with exit code 1 (use -v to see invocation) 错误

修改 SSL_USE_NATIVE属性

出现：--with-ssl was given but OpenSSL could not be detected 错误

[config.log](https://github.com/user-attachments/files/16816164/config.log)

(x86_64)
在build openssl

@pingkai 是否可以帮忙查看一下构建问题

Reproduce the iOS build on branch 0.4.4 with Apple M2, macOS 14.6.1, and Xcode 15.4, starting with ./build_external.sh iOS and the build_curl step. Review the attached config.log and the SSL_USE_NATIVE setting, then compare the arm64 and x86_64 OpenSSL failures. Done means the iOS build completes successfully for the reported architectures.
