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]
