Building JAX (cpu) with threading disabled?

[josephrocca]

Hello, I'm currently trying to get JAX (cpu only) working in the browser. This requires compiling with Emscripten, and apparently I need to compile without threading.

IIUC it's possible to restrict JAX to a single thread at run time, but I wasn't able to find any info on compiling without threading.

I'm wondering if there's a flag for this that I can set somewhere? If not, is there any viable (even if very hacky) way to do it?

Thanks!
