Building docker image with nixos/nix fails with error: Package ‘tinycc-musl-unstable-2023-07-10-compiler’ in «unknown-file» is not available on the requested hostPlatform

Describe the bug

I tried using the nixos/nix container to build docker containers in a 2-stage build process.
It works with some images, like redis, but fails with others, like bash.

This is the error I get:

15.42        a) To temporarily allow packages that are unsupported for this system, you can use an environment variable
15.42           for a single invocation of the nix tools.
15.42 
15.42             $ export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1
15.42 
15.42           Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
15.42                 then pass `--impure` in order to allow use of environment variables.
15.42 
15.42        b) For `nixos-rebuild` you can set
15.42          { nixpkgs.config.allowUnsupportedSystem = true; }
15.42        in configuration.nix to override this.
15.42 
15.42        c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
15.42          { allowUnsupportedSystem = true; }
15.42        to ~/.config/nixpkgs/config.nix.

When adding the NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1 env var, the build fails with a 904.2 ./arch/x32/crt_arch.h:12: error: unknown register %rbp

Steps To Reproduce

1. Build this Dockerfile:

FROM nixos/nix
RUN mkdir -p /output/store
RUN nix-channel --update
RUN nix-env --profile /output/profile -i bash

RUN cp -va $(nix-store -qR /output/profile) /output/store

FROM scratch
COPY --from=0 /output/store /nix/store
COPY --from=0 /output/profile/ /usr/local/
ENTRYPOINT [ "/usr/local/bin/bash" ]

Expected behavior

The container should be built successfully.

i have same error on tinycc-musl-unstable-2023-07-10-compiler , but I'm trying to download the binutils package in a desktop environment

[RyanGibb]

I also get this error in and outside docker container upon nix-env -i gnutar or nix-env -i binutils.

nix-env -i bash fails like the above on aarch64 docker but nix-env -iA nixpkgs.bash works. Inconsistent footguns are really out in force with protective landmines.
