[PATCH] build: import gtk-doc support

[Aleksander Morgado]

> Not sure if this is similar/same, but I have the same sort of issue when enabling introspection (which I now need) and cross-compiling - discussed here back in March.
> I'm moving over now to using a stable release (i.e. tarball), but it would be useful to have the option to use git checkout.

You mean you cannot build with introspection enabled from a git checkout?
