Emscripten now handles exit() in pthreads

[kleisauke]

This PR reverts a Emscripten specific change to the Open POSIX Test Suite. Since PR emscripten-core/emscripten#12933 (Emscripten v2.0.10) commit e350af1 can be safely reverted as exit() calls are now being proxied back to the main thread.

/cc @sbc100 as he is the author of emscripten-core/emscripten#12933.

Great news!

Again, thanks for working on this.

Now that we have integrated this testsuite into emscripten should we consider moving to the emscripten-core org. @juj ?

[juj]

Yeah, looks good.

Nice!

@kleisauke do you want to submit a PR updating the the submodule?

[kleisauke]

Yes, I could update that sometime next week (I'm quite busy with the musl upgrade now).

[sbc100]

A musl upgrade for emscripten? I've also be working on that on an off.. not sure how close you are but I got down the a single test failure IIRC. I don't many giving up my attempt as long as you don't mind he having some options about it :)

Let me upload my work in progress...

[kleisauke]

Sorry that I caused double work. My main focus was on updating the threading implementation to musl 1.2.1 (for e.g. pthread_testcancel, pthread_detach, pthread_cancel and pthread_join were moved from JS to musl now), so hopefully it doesn't collide too much with your changes.

[sbc100]

No worries! I was also my fault for not mentioning I had started to look at it. Happy to go either direction.
