Hi Rob,
I've just seen now that llvm include paths were removed compared to
the original version of this patch.
I had reported build errors without those on android-x86 development
mail thread.
I'm submitting a correction to mesa-dev ML, please review and apply it
It will be necessary also in 17.2 branch when this patch will be
backported to 17.2.0.
Thanks
Mauro
