Well, (I am not a toolchain expert) but 
powerpc:common is the 32-bit environment, and
powerpc:common64 is the 64-bit.  

Double check that /usr/lib/crti.o was rebuilt recently, instead of being
something old  lying around ... 

(I am not a toolchain expert) but, historically I have found that
building the toolchain on any arch (not just i386) always required 
extensive hacking around of a rather ugly and hair-pulling sort.  
Its possible that its gotten easier over the years, but ... maybe not.  

Are you *sure* your need to build your own compiler?  Using the 
provided compiler & assembler might make life a lot easier for you...
