This means the rtems-syms tool needs to be taught how to create a 
suitable symbols file for the PowerPC. Sebastian are you able to have a 
look?

The way we have been handling this is to add condition code for a 
specific arch in the standard template. This way the rtems-sym code does 
not need to know about the arch. The file is:

https://git.rtems.org/rtems-tools/tree/linkers/rtems-syms.cpp

I hope that means a fix would fix them all. :)
