Remove code size optimization

Optimizing VLC code for size is probably not such a great idea,
considering that media playback is performance critical. There are
better ways to reduce code size than -Os, e.g. Thumb(2) code on ARM.

And of course, removing unneeded plugins and feature is the best way
to reduce code size.
