This hook is still needed for "ELFv2 support rework" which
was just committed in r13-2984. There is also a note
explaining this in the original mail:
"btw, rs6000_print_patchable_function_entry can be dropped
but there is another rs6000 patch which needs this rs6000
specific hook rs6000_print_patchable_function_entry, not
sure which one gets landed first, so just leave it here."
