You're right that _STRING_ARCH_unaligned has already been changed on AArch64
(but not in this patch) so I'll have a go at adding a new define for this.

However note these functions were never referenced by any AArch64 compiler as
you need a pre 3.0 GCC to get possible references to them when including string.h. 
I'm not sure these symbols are exported by default either.
