Add support for building dartmonkey firmware with clang
By default all builds will use gcc. To build with clang, set
the environment variable CC=clang.
At this point only dartmonkey has been tested with clang.

BUG=b:172020503
TEST=Using icetower, Segger J-Trace, and servo micro:
make BOARD=dartmonkey -j
./flash_jlink.py -b dartmonkey -i ./build/dartmonkey/ec.bin
--remote 127.0.0.1:2551
=> console on icetower works
TEST=CC=clang make BOARD=dartmonkey -j
./flash_jlink.py -b dartmonkey -i ./build/dartmonkey/ec.bin
--remote 127.0.0.1:2551
=> console on icetower works
TEST=make buildall -j
TEST=CC=clang make BOARD=dartmonkey tests -j
TEST=make BOARD=dartmonkey tests -j
