This patch adds support to objdump for disassembly of NFP (Netronome Flow Processor) ELF files (.nffw) as well as some basic readelf support.

bfd	* Makefile.am: Added NFP files to build.
	* archures.c: Added bfd_arch_nfp
	* config.bfd: Added NFP support.
	* configure.ac: Added NFP support.
	* cpu-nfp.c: New, for NFP support.
	* elf-bfd.h: Added elf_section_info()
	* elf64-nfp.c: New, for NFP support.
	* po/SRC-POTFILES.in: Added NFP source files.
	* targets.c: Added nfp_elf64_vec
	* bfd-in2.h: Regenerate.
	* Makefile.in: Regenerate.
	* configure: Regenerate.

binutils* readelf.c: Very basic support for EM_NFP and its section types.
	* testsuite/binutils-all/nfp: New directory.
	* testsuite/binutils-all/nfp/objdump.exp: New file.  Run new
	tests.
	* testsuite/binutils-all/nfp/test2_ctx8.d: New file.
	* testsuite/binutils-all/nfp/test2_no-pc_ctx4.d: New file.
	* testsuite/binutils-all/nfp/test1.d: New file.
	* testsuite/binutils-all/nfp/nfp6000.nffw: New file.
	* testsuite/binutils-all/nfp/test2_nfp6000.nffw: New file.
	* NEWS: Mention the new support.

include	* dis-asm.h: Added print_nfp_disassembler_options prototype.
	* elf/common.h: Added EM_NFP, officially assigned. See Google Group
	Generic System V Application Binary Interface.
	* elf/nfp.h: New, for NFP support.
	* opcode/nfp.h: New, for NFP support.

opcodes	Makefile.am: Added nfp-dis.c.
	configure.ac: Added bfd_nfp_arch.
	disassemble.h: Added print_insn_nfp prototype.
	disassemble.c: Added ARCH_nfp and call to print_insn_nfp
	nfp-dis.c: New, for NFP support.
	po/POTFILES.in: Added nfp-dis.c to the list.
	Makefile.in: Regenerate.
	configure: Regenerate.
