I see the following in the function ppc_elf_check_relocs in source file elf32-ppc.c in the BFD sources.

The following patch gets me by the R_PPC_LOCAL24PC relocation in crti.o problem. It ensures that the 'got' is created when it sees a global R_PPC_LOCAL24PC relocation. I suspect that this ensures that the subsequent 'gsym->needs_dynamic_reloc' call returns false.
