[POWERPC] Generic BUG for powerpc
This makes powerpc use the generic BUG machinery. The biggest reports the function name, since it is redundant with kallsyms, and not needed in general. There is an overall reduction of code, since module_32/64 duplicated several functions. Unfortunately there's no way to tell gcc that BUG won't return, so the BUG macro includes a goto loop. This will generate a real jmp instruction, which is never used.
