Using clang-13 to compile https://github.com/WebAssembly/wasi-libc to wasm32-wasi with -mbulk-memory results in a fatal error. The command line and stack trace is attached below.

fatal error: error in backend: only -ftls-model=local-exec is supported for now on non-Emscripten OSes: variable errno
PLEASE submit a bug report to bugs.llvm.org and include the crash backtrace, preprocessed source, and associated run script.

Update: I confirm this issue is gone in llvm-15, but still present in llvm-14.

Minimal repro for llvm-14:

_Thread_local a;
b() { a = 0; }

I suggest we mark this a closed then .. unless you think this issue is important enough to warrant a backport? (My feeling is that it probably is not).

Nope, we can wait for wasi-sdk to bump to llvm-15 when the new major release is out, feel free to close :)
