Subject: Use -Os rather than -O3

This was probably a stupid decision in the first place. Who wants lengthy compile times for debatable gain? Apple use Os in all Xcode projects, so I'm guessing its the best choice.

Also I have long suspected the Image Magick performance issues Homebrew is supposedly susceptible to were because of O3.
