Subject: [PATCH] (target only) Work-around thumbnailer and pixdata
 cross-compile failure

Use native gdk-pixbuf-print-mime-types and gdk-pixbuf-pixdata
when generating the thumbnail metadata and resources.

This works but the mime types will come from native
loader.cache (which will only contain in-tree loaders), not from the
target loader.cache.

The upstream issue is https://bugzilla.gnome.org/show_bug.cgi?id=779057

Upstream-Status: Inappropriate [workaround]
