cttyhack: handle multiple consoles found in sysfs
...
If multiple consoles are found from the sysfs file, cttyhack fails:
cttyhack: can't open '/dev/tty0 ttyS0': No such file or directory
In such cases take the last one as the kernel will use that one for
/dev/console.

cttyhack: print detected ctty name when called without parameters
...
Sometimes there's a need to figure out the controlling tty from a shell
script, for example, to obtain a line for getty. In this case it's easier
to call cttyhack than trying to repeat some of the cttyhack's logic.
