GPS_PATH_MAX needs to be longer to handle Linux persistent device names.
The current value of GPS_PATH_MAX works for /dev/ttyfoo, but is
slightly too small to allow using persistent dev names. For example,
an ND-100S also shows up on my machine as
/dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller_D-if00-port0
which requires GPS_PATH_MAX >= 82.
