Bug#764272: gobject-introspection: tests/*.c #include config.h which is missing

[intrigeri]

Control: tag -1 + fixed-upstream
Control: tag -1 + upstream

Hi,

this seems to be https://bugzilla.gnome.org/show_bug.cgi?id=737275,
that was apparently fixed upstream in
https://git.gnome.org/browse/gobject-introspection/commit/?id=578eebd54bd9f2b1677922680701c454f489c895

It's on their 3.14.1 whiteboard, but no release yet. I guess we should
cherry-pick this commit for Jessie. What do the maintainers think?

Also note that lua-lgi workaround'd this in 0.8.0-2 by creating, on
the fly, an empty config.h. Presumably this could be used for
libgobject-introspection-perl as well, but I'd rather see the root
cause fixed.

Cheers!
