gnome-icon-theme now requires build dependency of libgnome

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

On a few system I have gnome-icon-theme without libgnome. (The window 
managers are jwm or xfce.)

But this morning I noticed that gnome-icon-theme 2.24.0nb1 adds 
build dependency of graphics/librsvg which depends on libcroco which uses 
libgnomeui.

So if you have old enough (but still good enough) gnome-icon-theme, you 
don't need libgnome but on a new install if pkgsrc, you will need it.

Anyway to make  gnome-icon-theme build without libgnome? (Or maybe it just 
don't matter since for long build only and not run-time usage.)

p.s. Sorry for my errant pr 40266 which made me notice this.
