Update Makefile

I think that

- the ARDUIO define should actually be named ARDUINO (main.cpp for example checks for an existing definition of ARDUINO)
- the teensyduino version is 1.20 now

Addition to gitignore and  Fix Yield when no Serial on USB

Update kinetis.h

Add CMP2 addresses

Update DMAChannel.h

I'm planning to merge the teensyduino 1.20 branch of DmaSpi to master tomorrow and then you can remove that hint, or update it please.

Update DMAChannel.h

Changed  DMABaseClass::source() and destination() to use p's address instead of its value in the if-clause. Taking the value could result in unwated read operations from I/O locations, resulting in data loss.
