[Buildroot] [PATCH] package/x11r7/xwayland: add mesa3d ordering dependency

[Buildroot] [PATCH] package/x11r7/xwayland: add mesa3d ordering dependency

[Adam Ford]

Xwayland's glamor/DRI configure check looks for Mesa's dri.pc in staging.
Without an explicit ordering dependency, a highly parallel build can run
Xwayland's configure before mesa3d is installed, failing with:

    ERROR: Dependency "dri" not found

Add mesa3d to XWAYLAND_DEPENDENCIES when it is enabled.

I found this problem as well but haven't succeeded making a valid
patch for it yet.
xwayland only needs dri when glx=true.
Should the check be closer to there to make it clearer that they are
connected? Maybe even inside the HAS_GL check?

However, I can't seem to find any other of the HAS_LIBGL providers
that produce a dri.pc, such as libglvnd, which conflicts with mesa3d
libgl provisions. (I wasn't able to build nvidia-driver last I tried,
so I don't know if they have a dri.pc)

Should mesa3d always be selected by xwayland?

Thanks! // John Ernberg
