pkgs/stdenv/linux: bootstrap-files for third (and final) mips ABI: n32

Browse source 
This PR provides the Hydra-generated bootstrap tarballs for mips64el-linux-gnuabin32.

With this PR we now have the bootstrap-file for all three little-endian ABIs on mips: n64, n32, and o32.  I do not currently plan to do big-endian mips unless some motivation arises; all mips chips are bi-endian and Debian has dropped big-endian support due to lack of interest.

I'll be following the script used in #151399, #168199, and #183487.

Files came from [this](https://hydra.nixos.org/build/188389586#tabs-summary) Hydra build, which used nixpkgs revision 97d9c84e1d to instantiate:

```
/nix/store/hakn8s85s9011v61r6svp5qy8x1y64fv-stdenv-bootstrap-tools-mips64el-unknown-linux-gnuabin32.drv
```

and then built:

```
/nix/store/rjgybpnf3yiqyhvl2n2lx31jf800fii2-stdenv-bootstrap-tools-mips64el-unknown-linux-gnuabin32
```

I downloaded these files from Hydra and prefetched them into the nix store with the following commands:

```
STOREPATH=rjgybpnf3yiqyhvl2n2lx31jf800fii2-stdenv-bootstrap-tools-mips64el-unknown-linux-gnuabin32
OPTIONS="--option binary-caches https://cache.nixos.org --option trusted-public-keys cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY="
nix store prefetch-file \
  file://$(nix store add-file --name bootstrap-tools.tar.xz  $(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/bootstrap-tools.tar.xz)
nix store prefetch-file --executable \
  file://$(nix store add-path --name busybox $(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/busybox)
```

These commands produced the following output:

```
Downloaded 'file:///nix/store/w6zzd2fx2vhmjfcf5h5zc01m0swldpbw-bootstrap-tools.tar.xz' to '/nix/store/6w0f0mqblrghvh6yjwcb4xdqq9x50lbl-w6zzd2fx2vhmjfcf5h5zc01m0swldpbw-bootstrap-tools.tar.xz' (hash 'sha256-LWrpN6su2yNVurUyhZP34OiZyzgh7MfN13fIIbou8KI=').
Downloaded 'file:///nix/store/nqagw1kgdz1zlmqi00qfjrmwqk3g3bgd-busybox' to '/nix/store/i361xhbdhhnvg7zd637xpm63vbl80s0s-nqagw1kgdz1zlmqi00qfjrmwqk3g3bgd-busybox' (hash 'sha256-4N3G1qYA7vitjhsIW17pR6UixIuzrq4vZXa8F0/X4iI=').
```

I used the hashes from the output above to create the `fetchurl` invocation which is part of this commit.

I then started the bootstrap with the following command:

```
nix build -L -f . --arg localSystem '(import ./lib).systems.examples.mips64el-linux-gnuabin32' hello
```

As @lovesegfault requested, here are the the `sha256sum`s of all the `on-server` components for extra verification:

```
sha256sum /nix/store/${STOREPATH}/on-server/*
```

which produced the following output:

```
