xorg-6.9rc1 : unichrome mesa driver not building

[Xavier Bachelot]

Hi all,

I'm trying to build xorg 6.9 RC1 with unichrome 3D driver enabled but it 
  fails. Output below. I've looked at mesa tree and it seems that the 
missing via_dri.h has been moved to the server subdir.

including in lib/GL/mesa/drivers/dri/unichrome...
