  Log:
  SVN rev 197348 on 2009-09-20 12:40:56Z by kib
  
  Old (a.out) rtld attempts to mmap zero-length region, e.g. when bss
  of the linked object is zero-length. More old code assumes that mmap
  of zero length returns success.
  
  For a.out and pre-8 ELF binaries, allow the mmap of zero length.
