Here We need `extern "C"` to generate `aapcs` or `aapcs-vfp` calls
depending on target configuration.

Doing this LLVM generate:

That's exactly what We need

In order for GDB to correctly backtrace a stack overflow, it needs
CFI information in __rust_probestack.

This turns the following backtrace,

```
>> bt
 #0  0x0000555555576f73 in __rust_probestack () at /cargo/registry/src/cf-workers-proxy-9e9.pages.dev-1ecc6299db9ec823/compiler_builtins-0.1.14/src/probestack.rs:55
Backtrace stopped: Cannot access memory at address 0x7fffff7fedf0
```

To this:

```
