After _bfd_i386_elf_convert_load and _bfd_x86_64_elf_convert_load are removed, elf_i386_convert_load_reloc and elf_x86_64_convert_load_reloc see __ehdr_start as an undefined symbol when they are called from check_relocs to convert GOT relocations against local symbols. But __ehdr_start will be defined as a hidden symbol by linker at the later stage if it is referenced. This patch marks __ehdr_start as a defined local symbol at the start of check_relocs if it is referenced and not defined. bfd/ PR ld/22115 * elf32-i386.c (elf_i386_convert_load_reloc): Check linker_def.
