This patch breaks out the most basic configuration options into a set of base options, to allow them to be used also by scripts that do not involve any ISA, and thus no actual CPUs or devices. The patch also fixes a few modules so that they can be imported in a NULL build, and avoid dragging in FSConfig every time Options is imported.
