Thanks for clarifying, I was dull and misunderstood it.
Confirmed, some symbols are from rs6000-builtin.cc (which is not generated) but
it requires some symbols in rs6000-builtins.cc (which is generated). Both
object files are not included in linking. The below diff can fix it:
diff --git a/gcc/config.gcc b/gcc/config.gcc

According to David's comments "rs6000-ibm-aix doesn't exist any more" and I
vaguely remembered Segher also mentioned rs6000*-*-*) becomes stale, maybe we
can aggressively drop the whole rs6000*-*-*) case handling?
