Fix override of common symbols for a.out The default should be bfd_link_common_skip_none, as in the original patch at https://sourceware.org/ml/binutils/2002-07/msg00717.html * aoutx.h (aout_link_check_ar_symbols): Remove default and handle bfd_link_common_skip_none in switch.

Fixes for "Ignore dynamic references on forced local symbols" PowerPC64 has its own mark_dynamic_ref, which needs the same change as made by d664fd41e1 to the generic ELF version. Some other targets discard more than just .data, so allow for that too in expected ld messages. bfd/ PR ld/22649 * elf64-ppc.c (ppc64_elf_gc_mark_dynamic_ref): Ignore dynamic references on forced local symbols. ld/ PR ld/22649 * testsuite/ld-elf/pr22649.msg: Allow other messages. * testsuite/ld-elf/shared.exp: Check that --gc-sections is supported before running ld/22649 tests.

_bfd_mips_elf_final_link: Notify user about wrong .reginfo size One of assertions in _bfd_mips_elf_final_link could be triggered by a combination of input files and a linker script. This happens when either the input doesn't contain .reginfo section or when this section is oversized. This patch replaces the assertion with a more useful error message. * elfxx-mips.c (_bfd_mips_elf_final_link): Notify user when .reginfo section has wrong size.
