May be we could enhance autoconfig.
For --enable-ubsan, we currently have -fno-sanitize=alignment, because
it produces tons of flase positives on x86.
We could drop that for arm. then all unaligned access will result either
in illegal stataments or in warning messages, depending on whether you
also drop -fsanitize-undefined-trap-on-error.
