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

Browse Source 
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.
