Part of the problem is, is that a *TON* of files depend on the atomic.h headers. If we'd generate it on every build, you'd basically get to rebuild the whole kernel every single time. Also, these files don't change too often. And if you look, there's a hash in those files which is used to check if things somehow got stale.
