Oops, thanks.

I got this to at least start compiling but now
I think it should be a oe-core-1.6 feature. I've opened:

    https://bugzilla.yoctoproject.org/show_bug.cgi?id=5321

Details below.

So that's a much cleaner change, eg:

meta/recipes-graphics/mesa/libglu_9.0.0.bb
...
-inherit autotools pkgconfig
+inherit autotools pkgconfig distro_features_check
+REQUIRED_DISTRO_FEATURES = "opengl"

and adding additional features is easy too.

I stuck with this syntax and fixed all the recipes when
they failed at initial parse time. That left a few packagegroups
to be fixed and I ended up with:

  recipes-core/.../packagegroup-core-tools-testapps.bb |    2
  recipes-core/.../packagegroup-self-hosted.bb         |   14 ---
  recipes-extended/.../packagegroup-core-lsb.bb        |   41 ----------
  recipes-graphics/.../packagegroup-core-clutter.bb    |    3

The summary of this change was some simple changes:

meta/recipes-graphics/packagegroups/packagegroup-core-clutter.bb
...
-inherit packagegroup
+inherit packagegroup distro_features_check
+REQUIRED_DISTRO_FEATURES = "opengl"

and some refactoring of packagegroups to ensure that the
graphical part of lsb and self-hosted could be easily disabled.
