Sorry, I thought there was a way to do it via configure but I see there
was not (easily).

I've made a change that causes GNU/Hurd to not use the mkfifo()-based
jobserver, and go back to using pipe().

I am not sure if there is an alternative, or what to do about Cygwin. 
I haven't been able to create any test environments that can reproduce
these issues so I don't know what the actual problem is.
