Then ar is calling ranlib for you unless you are passing it the -S flag.

If you are building for multiple arches then you should pass ar the -s
flag (as Rainer said) to ar to ensure that the table of contents is
created. As you can see from the ar sources it calls ranlib -q normally,
and ranlib -f if it saw the -s flag. Ranlib -q will "Do nothing if a
universal file would be created." whereas ranlib -f will create the fat
archive.
