That will work around the issue for 'shared' and 'std140' but if a shader has a
ubo with a 'packed' layout and is unused in the shader it will still hit this
same problem right?

The problem is the linking code always expects there to be a least one active
use of the ubo array in the shader, I attempted to fix this but it REALLY
expects there to be a use so its not quite as simple as you would expect.

I may give it another go when I have some time as I'm playing around with this
code for AoA support currently.
