PR22300, Abort in elf32_hppa_relocate_section building polyml
polyml produces object files with the wrong OS/ABI for hppa-linux. This, along with the fact that elf32-hppa.c is using the strictest backend relocs_compatible, results in wrong merging of ELF symbols. So, remove the relocs_compatible check in _bfd_elf_merge_symbol. _bfd_elf_merge_symbol is only called nowadays from within blocks protected by is_elf_hash_table, so "we are doing an ELF link" as the removed comment says, is true. Also relax relocs_compatible for hppa and powerpc. relocs_compatible is used for more than just merging symbols, as the name suggests. This allows objects that are in fact reasonably compatible to be linked. PR 22300 * elflink.c (_bfd_elf_merge_symbol): Remove relocs_compatible check. * elf32-hppa.c (elf_backend_relocs_compatible): Define. * elf32-ppc.c (elf_backend_relocs_compatible): Define. * elf64-ppc.c (elf_backend_relocs_compatible): Define.
