When using the stand alone compiler, if we try to
link a shader with vertex attributes it will
segfault on linking as the binding hash tables are
not included in the shader program. Obviously, we
cannot make the linking stage succeed without the
bound attributes but we can prevent the crash and
just let the linker spit its own error.
