For more context, this is because of https://github.com/NixOS/nixpkgs/blob/27cf93c040c0f7502ab8556b681764abafba02a1/pkgs/top-level/all-packages.nix#L19187-L19190 , in which the prebuilt android platform will just use the android ndk's libraries as the bionic package, instead of trying to build it separately
