JF002 1b6acdedc2 Enable various compilation flags to reduce the binary size (#401) ...

* Add the following compilation flags:
 * -fno-exceptions and -fno-non-call-exceptions : disable exception handling
 * -fno-rtti : disable run time type information (needed by dynamic_cast, for example)

These flags reduce the binary size by about 100KB!

Also, -fstack-usage generate debug info (not in final binary) to allow tools like Puncover to do a stack analysis.

* Remove unused CMake variables in CMake_nRF5x.cmake (duplicated in src/CMakeLists.txt).
Replace -O0 by -Og in DEBUG builds. This generates a smaller binary (small enough for the internal memory) that is debugger friendly.
