In Makefiles the $ must be escaped as $$ in shell uses.
Since 8a2390a4f47:
$ make docker
[...]
NETWORK=1 Enable virtual network interface with default backend.
NETWORK=ACKEND Enable virtual network interface with ACKEND.
Once escaped:
$ make docker
[...]
NETWORK=1 Enable virtual network interface with default backend.
NETWORK=$BACKEND Enable virtual network interface with $BACKEND.
