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.
