  Bug #23294: Detection of sem_xxx functions on NetBSD broken and \
  	DragonflyBSD misc patches
  
  The bug reporter anticipated a problem, instead of experiencing one.
  
  IRC conversation:
  <xtraeme> sem_init is defined in librt on NetBSD
  	solaris uses libposix4 iirc
  	that's why I sent a patch
  <chadmiller> xtraeme: Agreed.  But, AFAICT, mysql doesn't use 
  	sem_init() anywhere.  Thus my confusion.
  <xtraeme> I didn't verify that, but I saw that sem_init wasn't detected 
  	correctly...
  	why are you checking for sem_init if it's unused then? :-)
  <chadmiller> xtraeme: In recent autoconf scripts, we change it to test 
  	for sched_yield() .
  <xtraeme> that's ok then
  	sched_yield is in libc
  	feel free to close the bug report then :-)

    Remove useless test for sem_init() .
