Cannot compile to wasm: @thread_local is not supported for this target platform

[StanislavNikolov]

Context

This program does not build

package main
main :: proc() { }

when the target is either wasi_wasm32, js_wasm32 or freestanding_wasm32. Build command:

$ odin build test.odin -target:wasi_wasm32                                                                                                                                           1 ↵
/Users/stjo/Odin/core/runtime/core_builtin.odin(8:15) @(thread_local) is not supported for this target platform

odin report output:

	Odin: dev-2022-03:84cee5d
	OS:   macOS 12.0.4 Monterey
	CPU:  ARM64
	RAM:  16384 MiB

Removing @thread_local from core/runtime/core_builtin.odin line 8 fixes the issue:

// @thread_local global_default_temp_allocator_data: Default_Temp_Allocator
global_default_temp_allocator_data: Default_Temp_Allocator

Now test.wasm file is produced. wasmtime fails to run it, but I believe this is a separate issue altogether.

Expected Behavior

.wasm file should be produced.

Current Behavior

Compiler bails out with

/Users/stjo/Odin/core/runtime/core_builtin.odin(8:15) @(thread_local) is not supported for this target platform
