  Log:
  SVN rev 200509 on 2009-12-14 12:19:21Z by rwatson
  
  Merge r197808 from head to stable/8:
  
    In rtld's map_object(), use pread(..., 0) rather than read() to read the
    ELF header from the front of the file.  As all other I/O on the binary
    is done using mmap(), this avoids the need for seek privileges on the
    file descriptor during run-time linking.
