Thanks for the review!

Regarding the change to locale.cpp: CloudABI does not have setlocale(), which is why this call would need to be disabled. libc++ still has a global locale, but it's not the case that this is propagated to the C runtime.

I've reverted this part of the change for now, as we could argue it's not related to the change at hand. I suspect it may make more sense to `#ifndef __CloudABI__` that part at one point.
