The linker was rewritten for x86-64 support and 10.5 was rushed out  
the door apparently before they
could put text relocations back in. I believe GNU ld supports it  
perfectly well too, and they're rather apologetic
about it in the documentation, so it'll hopefully be back in soon.

Actually, since that's using =m constraints and not MANGLE, isn't this  
a gcc bug? I guess I'll file some more bug reports.

If you don't need encoders, just do --disable-encoders and it'll build  
again. Otherwise, um, I wonder why it doesn't have --disable-sse2...
