I get this output when I try and compile a simple C file:
```

clang-13: error: clang frontend command failed with exit code 70 (use -v to see invocation)
clang version 13.0.1
Target: ppu-unknown-lv2-elf
Thread model: posix
InstalledDir: /usr/bin
```
In this zip file is the files it tells me to attach:
[adc519.zip](https://github.com/llvm/llvm-project/files/8692579/adc519.zip)
It appears to come from the fact that it's trying to call a function set as `extern` since it fails at the call to `_init()`
I also get this error on clang 15:
```
