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:

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?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113507 --- Comment #4 from David Edelsohn --- rs6000-ibm-aix doesn't exist anymore. This should have been configured as powerpc-ibm-aix7.2 . Maybe there is some magic about the "powerpc" name? Those variables are provided by generated files and apparently something is not generating them when building a cross compiler.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113507 --- Comment #1 from Andrew Pinski --- This seems like a depedency issue. rs6000_builtin_types is defined in rs6000-builtins.cc which gets built by build/rs6000-gen-builtins which is built from $(srcdir)/config/rs6000/rs6000-gen-builtins.cc .
