Step:
1. Open repro project. Inside the repro scene, there are shaders which are having #pragma target lines.
2. Build with Vulkan api, to a Mobile device with Mali GPU

Expected Result: All spheres look the same (textured surface shader sphere) and are not pink
Actual Result: The target 4.0, 4.6 and 5.0 ones are pink. Others are correctly renderered.
