Makefile: Make sudo optional for tty access

Browse source 
Being in the proper group is sometimes enough to avoid needing sudo to
access tty devices. If not done by the distro, a udev rule isn't too
hard to tweak to get convenient permissions on the device (using lsusb
to fill in XXXX and YYYY):
SUBSYSTEMS=="usb", ATTRS{idVendor}=="XXXX", ATTRS{idProduct}=="YYYY", GROUP="uucp"
