Makefile.inc: Use -Og when compiling with GDB support

From GCC's documentation:

Optimize debugging experience. -Og enables optimizations that do not interfere
    with debugging. It should be the optimization level of choice for the standard
    edit-compile-debug cycle, offering a reasonable level of optimization while
    maintaining fast compilation and a good debugging experience.
