_mesa_glsl_has_builtin_function is used to determine whether any variant of a builtin are available, for the purpose of enforcing the GLSL ES 3.00+ rule that overloads or overrides of builtins are disallowed. However the builtin_builder contains information on all builtins, irrespective of parse state, or versions, or extension enablement. As a result we would say that a builtin existed even if it was not actually available. To resolve this, first check if at least one signature is available for a builtin before returning true.
