Zig bundles its own private copies of glibc or musl for each platofrm, crt.o, system headers, cross-linkers, and clang. They've done a lot of work to replicate cross-build toolkits for each target:
As a Rust user I'm super jealous of that, because Rust's "rustup target add" gives a false illusion of being able to cross-compile, but it can only build object files/static libraries, and if you ask for anything more, Rust just spits a big linker error and you're on your own.
