Auto merge of #1291 - semarie:openbsd-pthread-stack-min, r=gnzlbg

adjust PTHREAD_STACK_MIN to current value on OpenBSD

adjust `PTHREAD_STACK_MIN` to current value on OpenBSD, and while here, generate the right file in test_openbsd()

I should say that I am a bit disappointed. If I didn't miss anything, the related change for `PTHREAD_STACK_MIN` is near to one year old. And clearly with the name error in `test_openbsd()` something wasn't clean.
