Log:
  libc: rm stale generated files which are no longer syscalls
  
  This is an attempt to help -DNO_CLEAN builds after r302092 (which
  removed the pipe libc syscall wrapper) and r318736 (which removed
  getdents, lstat, mknod, and stat).
  
  Dependencies cannot cope with certain source tree changes,
  particularly with respect to removing source files and replacing
  generated files.  Handle these cases from _worldtmp in an ad-hoc
  fashion.
