[Nix-dev] Out-of-tree building for autotools packages in a Nix expression

[Anderson Torres]

Hello, Nixers!

How can I instruct Nix to use an out-of-tree building in a GNU
Autotools-based package? There are some packages I want to build, and
generally the upstream developers recommend the building directory
being out of the unpacked source tree.

An example is INTERCAL, an esoteric language I am playing around.

Thanks in advance!
