    Move UNDEFWEAK_NO_DYNAMIC_RELOC to elf-bfd.h
    
    Move UNDEFWEAK_NO_DYNAMIC_RELOC to elf-bfd.h so that it can be used by
    other ELF linker backends.
    
    	* elf32-ppc.c (UNDEFWEAK_NO_DYNAMIC_RELOC): Moved to ...
    	* elf-bfd.h (UNDEFWEAK_NO_DYNAMIC_RELOC): Here.
    	* elf64-ppc.c (UNDEFWEAK_NO_DYNAMIC_RELOC): Removed.
