## Message

```
tools/gen_stubs: add aarch64 and output preprocessor directives

Now it outputs libc.S which can be assembled with zig, and the small
differences per-architecture are handled with preprocessor directives.

There is also now a set of blacklisted symbols which contains
compiler-rt.

```
