This recipe builds natively just the gtk-update-icon-cache binary that is
required to run the gtk-icon-cache.bbclass postinstall scripts.
The advantage of doing this is it means running 400 less tasks which takes four
minutes on my machine, as the alternative is building GTK+ natively (and so
libX11, freetype, fontconfig...).
