Optimize debug builds when -Og is available
Enables optimizing with -Og if GCC has the option available, this should produce faster debug binaries without compromising debugability. Is a privateConfig to limit it to the default Qt build. Includes two fixes for false positives of maybe_uninitialized triggered by -Og on gcc 4.9. Change-Id: I466d7a4070295714189024369312e6cbd36cfacf Reviewed-by: Oswald Buddenhagen <>
