Hi,

CFRunLoop is supposed to be integrated with libdispatch because that's
how it is on OS X.

dispatch_get_main_queue_eventfd_np() is needed for working integration.
I've checked the package available in Ubuntu and it's either broken or
ancient, because this symbol is not present.

So I'd suggest removing your hack and using --without-gcd if your distro
has old/broken libdispatch.
