Subject: 	* elf-bfd.h (struct elf_backend_data): Add want_got_sym.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2517a57fdf395c6e5068577d1d4f86b3c6935e6d;p=binutils-gdb.git

	* elf-bfd.h (struct elf_backend_data): Add want_got_sym.
	* elfxx-target.h (elf_backend_want_got_sym): Define.
	(elfNN_bed): Add elf_backend_want_got_sym.
	* elflink.c (_bfd_elf_create_got_section): Define
	_GLOBAL_OFFSET_TABLE_ only if bed->want_got_sym.
