  Bug #32632: Compile failure on Mac/Intel with BUILD/compile-pentium
  
  The autoconf macro to check for pthread_yield_np was not
  discovered by autoheader.
  Fixed by extending the macro call and moving it inside the macro
  definition that handles pthread_yield.
  No test case necessary as this is a configure script change.

Pushed into 6.0.5-alpha

No changelog entry needed.
