	* bfd-in.h: Declare it.
	* bfd-in2.h: Regenerated.
	* elfcode.h (NAME(_bfd_elf,bfd_from_remote_memory)): New function.
	* elf-bfd.h (struct elf_backend_data): New function pointer member
	elf_backend_bfd_from_remote_memory.
	(_bfd_elf32_bfd_from_remote_memory, _bfd_elf64_bfd_from_remote_memory):
	Declare them.
	* elfxx-target.h (elf_backend_bfd_from_remote_memory): New macro.
