Also explicitly specify `-mstrict-align` (The current default `-mcpu` on gcc doesn't support unaligned accesses, so aligned memory accesses are already implicitly required). The `-Wcast-align` warning seems to oversensitive as it flags code like this: https://godbolt.org/z/c8481o8aa This used to be added for aarch64 ina473cfd71b, but was later removed in11896868d6.
