Putting dispatch_tabxxx in .rodata seems to skirt the issue, but  
generates heaps of warnings on 32 bit. No idea if that works on 64 bit  
as I don't have access to a 64 bit machine at the moment. Maybe make  
the added section .rodata/.text lines conditional with "%ifidn  
__OUTPUT_FORMAT__,macho64", that avoids the warnings and allows the  
system to cache the dylib code on 32 bit.

Someone with more x86 assembly experience could probably find a better  
solution... I'm just kinda hacking in the dark here. I was able to  
build 64 bit dylibs though.
