This isn't needed here, but in patch 2, where I'm already adjusting
existing dependencies. Since I'm not modifying any toplevel files, the
building of opcodes/ still ought to be happening before the building of
gas/, so I don't see why any further changes should be necessary. Please
clarify if you see any such reason.
