我不知道我是否可以在这里问这类问题，但无论如何我都会这样做。
我试图在浏览器中运行 32 位 linux 二进制文件，因此我将 box86 编译为wasm（box86js）并直接在浏览器中运行几个简单的二进制文件。
现在我想要一个动态链接器，它本身依赖于 libc SDL2 GL，也许还有其他一些，当加载依赖于这些库的二进制文件时，它会用自己的符号解析这些库的符号。
通过这种方式，我希望我可以在浏览器中运行更复杂的二进制文件，其性能比jslinux更好，并且可以完全访问浏览器 API，而且我认为拥有一个可以在本机和浏览器中运行的单个文件非常酷。
glibc 有太多的活动部件，我希望你能帮助我。
我在我的 x86_64 debian sid 系统上使用这些命令编译了 glibc
../glibc-2.31/configure CC="gcc -m32" CXX="g++ -m32" CFLAGS="-O3" CXXFLAGS="-O3" --build=i686-linux-gnu --host=i686-linux-gnu --prefix /opt/glibc
您可以在此处查看仅编译 ld.so 的相关部分（主文件为 rtld.c）
我修改了 rtld.c 中的几个地方并尝试编译它，但给了我很多未定义的符号
