I originally had bfd_size_type and wondered if we could use size_t,
which is the natural type to use here.  (bfd_size_type might be 64-bit
and it doesn't really make sense to use that when describing a memory
area on a 32-bit host.)  gdb and binutils built without trouble on a
few targets, so I went with size_t.  Sorry about the sim breakage.

	* elf-bfd.h (struct elf_backend_data
	<elf_backend_bfd_from_remote_memory>): Replace "size_t size"
	with "bfd_size_type size".
	(_bfd_elf32_bfd_from_remote_memory): Likewise.
	(_bfd_elf64_bfd_from_remote_memory): Likewise.
	* elf.c (bfd_elf_bfd_from_remote_memory): Likewise.
	* elfcode.h (bfd_from_remote_memory): Likewise.
