Everything I tried failed.

First attempt:

# cat /usr/local/etc/nix/nix.conf
build-users-group = nixbld
build-use-chroot = true

# ./pre-inst-env guix-build -K                \
      -e '(@ (gnu packages make-bootstrap) %bootstrap-tarballs)'  \
      --system=mips64el-linux

I'll try to build statically-linked Bash.  Then I'll place it in
'/bin/sh' and try again.  (This worked on i686.)
