Before the MMU is up, all reads/writes must be aligned; the optimized memcpy implementation does not guarantee all reads/writes it performs are aligned. This commit splits the libc impl to be separate for kernel/kernel_ldr, and so now only kernel will use the optimized impl. This is safe, as the MMU is brought up before kernel begins executing.
