Issue description

It seems like any version of GCC 5.4.0 compiled by Nix cannot print its own configuration options when you run it with the -v option. Usually GCC prints a line that says "Configured with:" followed by the arguments that were passed to its configure script.

Steps to reproduce

Run nix-shell -p hello and then run gcc -v. It just says "Configured with:" and has no configuration options on that line.

Workaround

I suppose I can just look at the derivation files for the GCC in question to see how it was configured/built.

Technical details

• System: Arch Linux x86_64
• Nix version: nix-env (Nix) 1.11.2
• Nixpkgs version: 16.09pre88195.26d2577
