Comment (by kencu):

 I think this error is happening with our llvm patch because with our
 patch, llvm might call for the emulated tls symbol.

 zig checks to see if the symbol exists, therefore, and doesn’t find it, so
 errors.

 see

 https://github.com/ziglang/zig/issues/8180

 and

 https://github.com/ziglang/zig/commit/dbfcebf8d88b91c5a85366da09a4ce69c0bb5dc6

 We might be able to tell zig not to error when it can’t find

 {{{'___emutls_get_address'}}}

 by passing a linker flag.
