Linking problems with DNSServer with arduino-mk

[flohoff]

Hi,
when building with the Arduino IDE everythings fine - But building with arduino-mk fails with a linker error concerning DNSServer:

I trying to build with various combinations of

ARDUINO_LIBS=DNSServer CoogleIOT ESP8266HTTPClient ESP8266WiFi
USER_DEFINE=-DARDUINO_ESP8266_ESP01 -DMQTT_MAX_PACKET_SIZE=512
