Re: Don't compile some opcodes files when bfd is 32-bit only

Put bpf back in the 32-bit targets, even though bpf requires a 64-bit
bfd.  bpf sim support apparently works without being 64-bit.

	* Makefile.am (TARGET64_LIBOPCODES_CFILES): Move bpf files..
	(TARGET32_LIBOPCODES_CFILES): ..to here.
	* Makefile.in: Regenerate.
