I don't think we are even using sched_yield anymore, so I'll send out a pull request to remove that configure check, and that should fix this build error.

Removed configure check for sched_yield
61f5dca 
In the past we used sched_yield for some initialization code, but we are
no longer using it. This change removes the configure script check for
sched_yield so that we can still build even if sched_yield does not seem
to be available. This fixes protocolbuffers#5435.

OK, this should now be fixed on the 3.7.x branch and we will merge that to master soon.
