Third party dependencies have been merged into the source tree as submodules! If you previously installed RPCSX when you needed `spirv-cross`, `gslang`, or `xbyak`, you should run:
```
git pull
git submodule update --recursive --remote
```
This removes the second way for arch to install spriv-cross as its easier / better to just use YAY.
This also fixes the warning to make it an actual warning and stand out a bit more.
