It doesn't matter, because libdispatch accounts as 'system library' - see GPL FAQ for explanation what system libraries are and why GPL applications can link against them, regardless of their license. (For example, GPL-ed applications under Windows can link against Microsoft-provided DLLs.)

The system library exemption only covers the case where you're distributing the code that uses the library separately. Traditional interpretation in the Linux world has been that this prevents you using this for a non-GPL compatible library if other libraries or applications in the standard install make use of it.
