为Musl目标链接Rust静态库时，如何修复GLIBC 2.4符号未定义引用？

问题背景 #

在Musl目标环境下，通过cbindgen将Rust库与C程序结合，使用cross工具进行交叉编译。Rust库编译成功，但构建C程序时出现链接错误。

依赖与过往解决情况 #

此前第一个Rust库遇到过类似GLIBC相关问题，当时是因为设置了[lib] crate-type = ["rlib"]，后来改为仅保留"staticlib"以静态方式链接库后解决。但当前Rust库引入了更多依赖：

futures = "0.3"
futures-executor = { version = "0.3", features = ["thread-pool"] }
libretranslate = { path = "lib-rs/libretranslate-rs" }
openssl = { version = '0.10', features = ["vendored"] }

额外信息 #

• Rust库的readelf输出（Debug构建，大小250Mb）
• Rust库代码仓库
• 待链接的C++程序仓库

已尝试的方法 #

调整过[lib]选项及crate类型，但问题仍未解决，目前没有可行思路。
