PPCBoot is a dead project. Porting it to new boards  is  a  waste  of
time. Please use the successor project U-Boot instead.

Also, please  post  U-Boot  related  questions  to  the  u-boot-users
mailing list. They are off topic here.

You understand what "undefined reference" means?

Undefined references have little to do with the compiler version.

Instead of spreading wild speculations you should start  reading  the
documentation, especially this section in the FAQ:
