Additional check to address a bug in mesa in which a stride which is a divisor of the declared offset for an overflowing varying won't fail.
From the GL_ARB_enhanced_layouts spec: " It is a compile-time or link-time error to have any *xfb_offset* that overflows *xfb_stride*, whether stated on declarations before or after the *xfb_stride*, or in different compilation units."
