Re: emchain error building gcc - incompatible libc

Yes, that patch worked. emchain is now doing its thing and I will let you know the results.
emchained failed with the following error. Seems ld can't find a compatible libc. That is strange because they look compatible to me (i.e. ELF 32-bit MSB PowerPC). 

   # file /usr/powerpc-linux-gnu/lib/libc.so.6

   object, PowerPC or cisco 4500, version 1 (SYSV), for GNU/Linux
   2.6.8, dynamically linked (uses shared libs), stripped

The only thing I can think of is that I installed binutils and libc6 from unstable. Could that be the the problem?
