+Subject: [PATCH] Tweak gtkdoc settings so that gtkdoc generation works under
+ OpenEmbedded build system
+
+This requires setting a few environment variables so that the transient
+binary is build and linked correctly, and disabling the tweaks to RUN
+variable from gtkdoc.py script so that our qemu wrapper is taken into use.
+
+Upstream-Status: Inappropriate [oe-specific]
