[oe] Inclusion of `gobject-introspection` breaks several packages.

[Paul Menzel]

Dear OE folks,


`gobject-introspection` got added in 143188 [1] to get `libgee_0.6.0` to
build [2].

As a consequence the configure script of a lot of packages like `gtk+`,
`atk`, `gstreamer` detects the presence of GObject Introspection and
enables it.

        $ ./configure --help
        […]
          --enable-introspection=[no/auto/yes]
                                  Enable introspection for this build
        […]

Auto detection seems to be the default.

        […]
        configure:12206: checking for gobject-introspection
        configure:12237: $PKG_CONFIG --exists --print-errors "gobject-introspection-1.0 >= 0.6.7"
        configure:12240: $? = 0
        configure:12251: result: yes
        […]

Now for example Pango 1.10.0 does not generate a `gir` file, which was
enabled again in a later release [3]. This breaks building for example
`gtk+` [4].

The question is how to proceed.

1. Somehow excluding `gobject-introspection` from images.
2. Would packaging gir-repository [5] help?
3. Pass `--enable-introspection=no` by default to the configure script.
4. Add `--enable-introspection=no` to all relevant packages.
5. Update to new versions supporting GObject Introspection correctly.

What do you think?


Thanks,

Paul
