// NOTE(allen|a4.0.9): This is provided to establish a default method of getting
// a "build directory". This function tries to setup the build directory in the
// directory of the given buffer, if it cannot get that information it get's the
// 4coder hot directory.
//
// There is no requirement that a custom build system in 4coder actually use the
// directory given by this function.
