-ggdb3 make slightly bigger .elf files, but allows gdb to understand macros, which paparazzi uses somewhat extensively. Make this the default, since it only impacts the size of the debug sections and not the size of the flashed binary (in the lpc21/stm32 case). On the linux system we really don't care about these few more bytes...
