Add conditional compilation to add support for AArch64 without vector registers and/or hardware FPUs by using the generic implementation. **Context:** A few functions were hard-coded to use vector registers/hardware FPUs. This meant that libc would not compile on architectures that did not support these features. This fix falls back on the generic implementation if a feature is not supported.
