Helpers for build.rs scripts.
This library is meant to be used in build.rs scripts context.
It contains a set of standalone functions that encodes some of the
shared wisdom and conventions across build.rs scripts, cargo, dinghy,
cc-rs, pkg-config-rs, bindgen, and others. It also helps providing
cross-compilation arguments to autotools ./configure scripts.
As an optional feature, it offers with-bindgen, which helps dealing with
some idiosyncrasies of bindgen code generation.
