The IEEE 802.15.4 protocol stack (net/ieee802154/), the corresponding
SoftMAC (net/mac802154/), and the driver drivers (drivers/ieee802154/),
all generate prodigious quantities of debug messages.
The DEBUG option was hard-coded in the Makefiles. This patch adds
a config option to each of these subsystems to allow selectively
disabling the debugging output.
All three options default to "yes", so existing users should see no
difference in behaviour.
