Building tests for Arduino Mega 
1. Download and install Arduino Studio https://www.arduino.cc/en/Main/Software
2. Link missing c++ includes
 # ln -s /usr/include/c++/6/limits ../include/
 # ln -s /usr/include/c++/6/type_traits ../include/
3. Run make, using actual path to Arduino Studio
 # make mega ARDUINO-DIR=/opt/arduino/hardware/arduino/avr/cores/arduino/     \
   VARIANT-DIR=/opt/arduino/hardware/arduino/avr/variants/mega
4. It will create mega.vars file with these build variables and next time you
   ran make simpler: make mega
5. Build test goals as necessary:
 # make mega megaa  megab  megam
6. Upon success elf and hex files are placed in bin/ directory 

Building tests for Teensy 3.1
1. Download and install Arduino Studio https://www.arduino.cc/en/Main/Software
   (note, Teensyduino may not be supporting latest  Arduino Studio) 
2. Download and install Teensyduino https://www.pjrc.com/teensy/td_download.html
3. Download and install gcc-arm- https://launchpad.net/gcc-arm-embedded/+download
4. Run make, using actual path to Arduino Studio
 # make teensy3 ARDUINO-DIR=/opt/arduino/hardware/teensy/avr/cores/teensy3

Building tests for esp8266
1. Download and build esp-open sdk https://github.com/pfalcon/esp-open-sdk
2. Run make, using actual path to ESP8266_NONOS_SDK
 # make esp8266 esp8266a SDK-DIR=/opt/esp-open-sdk/ESP8266_NONOS_SDK_V1.5.4_16_05_20


Code size metrics are available in *.metrics.txt
To build your own metrics, remove corresponding .metrics.txt file and run
 # make teensy3 metrics
or 
 # make mega metrics
