Even Solaris has it and that has the most broken and ancient userland of
any Unix I am aware of. Given that autoconf explicitly talks about
printf in "Limitations of Shell Builtins", it can be assumed to be
ubiquious. Note that printf is a bit different to use than echo, which
is why it isn't used by many.
