Let 'build.core' from boards.txt change ARDUINO_CORE_PATH

This is support for https://code.google.com/p/arduino-tiny
The arduino-tiny project provides a boards.txt file and a whole
separate Arduino core modified to work with attinies.
Arduino.mk will now switch to that core if it finds a
'build.core' parameter in boards.txt and a folder in
$(ALTERNATE_CORE_PATH)/cores by that name.
