Where does stdenv assume that /bin/sh is Bash?

Yes, fix builders not to rely on /bin/sh (or at least not to assume it's Bash).
Certainly any Nix expression that refers to /bin/sh should be fixed to use
${stdenv.shell} (which can be assumed to be Bash).
A workaround would be to implement this feature request:
https://github.com/NixOS/nix/issues/24. This would allow /bin/sh to be
redirected to whatever you want.
