  Log:
  Add FILE locking stubs for libc.
  
  Change the FILE locking to support kernel threads when linked with
  libpthread (which you haven't see yet). This requires that libc become
  thread-safe and thread-aware, testing __isthreaded before attempting
  to do lock/unlock calls. The impact on non-threaded programs is minor.
  This change works with libc_r, so it's the best compromise.
