Jacob Alexander 9cc29cbffc Fixing CMake 3.6 deprecation message
- CMake 3.6 finally adds proper cross-compiler detection
- When detected, use full compiler detection infrastructure
- Still maintains compatibility back to CMake 2.8 (at least for now)
- With new detection, selecting only the C compiler as it speeds up the CMake generaion process
- Added a GCC 4.9 minimum version requirement for Bootloader
