The undefined behavior sanitizer complains about unaligned loads, even if they're OK for a particular platform in practice. It's possible that they _are_ a problem, of course, but since it's a known tradeoff the UBSan errors are just noise. Let's quiet it automatically by building with NO_UNALIGNED_LOADS when SANITIZE=undefined is in use.
