Bugzilla

I'm attempting to stand up some builds with clang trunk, currently version 11.

In version 11, the clang tree has a [breaking change to wasm](https://github.com/WebAssembly/wasi-libc/commit/d9066a87c04748e7381695eaf01cc5c9a9c3003b) which requires that we pick up the [corresponding change in wasi-libc](https://github.com/WebAssembly/wasi-libc/commit/d9066a87c04748e7381695eaf01cc5c9a9c3003b) which is available in [wasi-sdk release 10](https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-10).

However, when I update the rev for the wasi-sysroot task, the builds fail with:
```
 LucetcError { inner: ErrorMessage { msg: "Unknown module for symbol `wasi_snapshot_preview1::proc_exit`" }
```
From this point, I'm not super familiar, so this is just a guess, but: I notice that this symbol appeared in a recent [change to the bytecodealliance/lucet repo](https://github.com/bytecodealliance/lucet/commit/81e1b97e5046c12f450046cc8452c70c8793d229). Does the PLSysSec fork need to pick it up?
