nix-ld for NixOS installations

[wilsonehusin]

While this project was inspired by Nix, in practice it doesn't work very well in NixOS for binaries requiring glibc and the executable would refuse to launch. nix-ld somewhat solves that.

I'm not sure how we should integrate this, but even if it's not a blended-in support, I want the experience to be ~easy to use in NixOS. Loose coupling with the way this project integrates with make or direnv would be fantastic.

One possibility can be as simple as this working example using bindl generate nix-ld.
