Fix SIGBUS from alignment issues on 64bit ARM

ARMv8 (and in general aarch64) has flipped some strictness requirements.
However, at some point in history the NEED_ALIGN configure check code was
optimized away by GCC.

This fixes detection of alignment, as well as fixes an unaligned access that
snuck in via the logging code.

Also fixes a 64bit GCC atomics test that possibly never worked before.
