Note that for this project I am using Nix stand-alone (on Ubuntu), not 
NixOS. I found that /bin/sh is not available by default, so I experimented 
with "build-chroot-dirs = /bin=/nix-bin" (in /etc/nix/nix.conf, copying bash 
from the nix store to /nix-bin/sh). However, that made no difference at all.

It turned out the culprit in this case was make. As soon as I figured this 
out, I could solve the problem by passing "SHELL=sh" to make on the command 
line, so that make uses the sh in the path instead of /bin/sh.

Cheers and many thanks for all the help
Ben
