    x86: Also check x86 linker_def for non-shared definition
    
    Since elf_x86_linker_defined sets linker_def in elf_x86_link_hash_entry
    for linker defined symbols, SYMBOL_DEFINED_NON_SHARED_P should also check
    linker_def in elf_x86_link_hash_entry.
    
    bfd/
    
    	PR ld/24458
    	* elfxx-x86.h (SYMBOL_DEFINED_NON_SHARED_P): Also check x86
    	linker_def.
    
    ld/
