elf_backend_can_make_multiple_eh_frame

[Alan Modra]

This flag is never set for any target.  Delete it.  Also, I think it
is safe to unconditionally enable what it was supposed to control.

	* elf-bfd.h (struct elf_backend_data): Delete
	elf_backend_can_make_multiple_eh_frame.
	* elfxx-target.h (elf_backend_can_make_multiple_eh_frame): Don't
	define or use.
	* elflink.c (_bfd_elf_default_action_discarded): Move
	SHT_GNU_SFRAME check earlier.  Return 0 for ".eh_frame"
	and ".eh_frame.*".
