x86: Disallow invalid relocations against protected symbols
Since glibc 2.36 will issue warnings for copy relocation against
protected symbols and non-canonical reference to canonical protected
functions, change the linker to always disallow such relocations.
bfd/
* elf32-i386.c (elf_i386_scan_relocs): Remove check for
elf_has_indirect_extern_access.
* elf64-x86-64.c (elf_x86_64_scan_relocs): Likewise.
(elf_x86_64_relocate_section): Remove check for
elf_has_no_copy_on_protected.
* elfxx-x86.c (elf_x86_allocate_dynrelocs): Check for building
executable instead of elf_has_no_copy_on_protected.
(_bfd_x86_elf_adjust_dynamic_symbol): Disallow copy relocation
against non-copyable protected symbol.
* elfxx-x86.h (SYMBOL_NO_COPYRELOC): Remove check for
elf_has_no_copy_on_protected.
