Makefile: disable unaligned loads with UBSan
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.
