H.J. Lu ca3fe95e46 Add extern_protected_data and set it for x86 ... With copy relocation, address of protected data defined in the shared library may be external. This patch adds extern_protected_data and changes _bfd_elf_symbol_refs_local_p to return false for protected data if extern_protected_data is true. bfd/ PR ld/pr15228 PR ld/pr17709 * elf-bfd.h (elf_backend_data): Add extern_protected_data. * elf32-i386.c (elf_backend_extern_protected_data): New. Defined to 1. * elf64-x86-64.c (elf_backend_extern_protected_data): Likewise. * elflink.c (_bfd_elf_adjust_dynamic_copy): Don't error on copy relocs against protected symbols if extern_protected_data is true.
