tools/power/x86: Enable compiler optimisations and Fortify by default
Compiling without optimisations is silly, especially since some
warnings depend on the optimiser. Use -O2.
Fortify adds warnings for unchecked I/O (among other things), which
seems to be a good idea for user-space code. Enable that too.
