Oh no no no no!

This means that, even if glmark2 is not enabled, then libdrm will
forcibly be enabled in a configuration with libelg, libegls, and udev.

This is not correct *at all*. And IIRC, we already fixed a similar case
not so long ago... Ah, there it is:

    b80c488d04 package/kodi: fix selection of dependencies

And now, I also notice that there is already such a bug in glmark2,
where wayland protocols will also forcibly be enabled in a configuration
with egl, gles, and wayland, even when glmark2 is not enabled.

Globally, I think glmark2 needs a bit of refactoring: it is very unusual
that the feature-set is before the main symbol. Usually, we have, in order:
  - ARCH_SUPPORTS et al.
  - main symbol
  - if-block with all options.
  - comment(s) about toolchain features et al.

Could you look into that, and respin a full series that fixes all these
issues in glmark2, and adds the missing dependencies, please?

Regards,
Yann E. MORIN.
