Well "-g" is a bit stupid in this scenario, since this means you tell
gcc to optimize for size but include debugging informations too.

I would recommend -O2 as the "best" option to use. It does a fine job
deciding wether a optimization is really worth the extra bloat, which
is especially important when it comes down to the small i-cache the
N770's processor has.
