  Modified files:
    lib/libarchive       archive_write_set_format_ar.c 
  Log:
  Add hook routine archive_write_ar_finish() which writes the 'ar'
  global header if nothing else has been written before the closing of
  the archive. This will change the behaviour when creating archives
  without members, i.e., instead of generating a 0-size archive file, an
  archive with just the global header (8 bytes in total) will be created
  and it is indeed a valid archive by the definition of libarchive, thus
  subsequent operation on this archive will be accepted. This especially
  solves the failure caused by following sequence: (several ports do)
  
  % ar cru libfoo.a           # without specifying obj files
  % ranlib libfoo.a
