## Message

```
fix not passing std.builtin.link_libc to compiler_rt.zig and c.zig

comment reproduced here:

This is so that compiler_rt and libc.zig libraries know whether they
will eventually be linked with libc. They make different decisions
about what to export depending on whether another libc will be linked
in. For example, compiler_rt will not export the __chkstk symbol if it
knows libc will provide it, and likewise c.zig will not export memcpy.

```
