[Piglit] [PATCH 09/18] arb_geometry_shader4: Link without vertex shader.

[Fabian Bieler]

Test that linking fails without vertex shader present.

ARB_geometry_shader4 spec 2.15.2:
"Linking will also fail if the program object contains objects to form a
geometry shader (see section 2.16), but no objects to form a vertex shader"
