should this be in the |use_x11| above?

The include from gl_surface_egl.cc already has 'nogncheck' so I assume it
doesn't matter?
Or can we remove the nogncheck and leave this as a general dependency here?

So this is in the |use_x11| if statement, but that's all sort of moot. I took a
closer look at that included header and I don't think any symbols from it are
even used. So just removed the header, removed the build deps and removed it
from DEPS.
