## Message

```
cli: add `--debug-libc` to `zig build`

This option is similar to `--debug-target` in letting us override
details of the build runner target when debugging the build system.
While `--debug-target` lets us override the target query, this option
lets us override the libc installation. This option is only usable in a
compiler built with debug extensions.

I am using this to (try to) test the build runner targeting SerenityOS.

```
