[Bug target/46644] Built-in memcpy() does not test for unaligned destination address on ARM

The code that triggered the original error is a bit more complex:

struct st
{
   uint16_t x;
   uint16_t y;
   // ...
};
...
st * s;
for some reason, s is not aligned (comes from a third party library)

memcpy is called this way:

uint16_t value = 0;
memcpy(&s->x, &value, sizeof(uint16_t));

what would be the proper fix (struct st cannot be modified)?
Casting &s->x to (void *)?

Thanks.
