Re: 4.2 hasn't bootstrapped on powerpc-apple-darwin G5 machine for a very long time

Because it's hardcoded in the original darwin.h to something else, and  
the right one does not get detected during configuration.

Why must you use libtool from the same source as ld? Because libtool  
has binary detection logic, and an old version can reject object files  
with new load commands or new architectures, like ppc64 on a 10.3  
system.
