Rather than that patch, I changed the code to use sched_yield rather
than pthread_yield. I realized that libgo is already using sched_yield,
in runtime/go-sched.c. There shouldn't be any portability penalty to
also using it in yield.c.
Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu.
Committed to mainline.
