The circle is the gdk-pixbuf -> glycin -> librsvg -> gdk-pixbuf.  libjxl
has nothing to do with that.

The problem is I thought "auto" means "enable if glycin is there,
disable if not," but then some magic in meson.build always promotes it
to "enabled" on Linux.  Thus we need to pass -D glycin=disabled if
glycin is not there.

I just pushed the fix to trunk.
