[Nix-dev] force nix-build without binary caches?

[Wout Mertens]

It only keeps folders if the build failed. If you want to debug the build
process, use "nix-shell '<nixpkgs>' -A qscintilla" and go through the build
phases (unpackPhase, cd dir, patchPhase, configurePhase, buildPhase,
installPhase).
