    instead of our custom .go format, use elf
    
    * libguile/objcodes.c: Change to expect objcode on disk to be embedded
      in ELF instead of having the funky cookie.
    
      (to_native_order): Use already existing SCM_BYTE_ORDER style byte
      order instead of chars.
      (bytecode_to_objcode): No need for word_size arg.
      (scm_bytecode_to_objcode, scm_objcode_to_bytecode): Take optional
      endianness arg instead of sometimes using target-endianness.
      (scm_load_objcode, scm_write_objcode, scm_bytecode_to_native_objcode):
      Remove.
    
    * libguile/objcodes.h: Adapt.
    
    * libguile/vm.c (scm_load_compiled_with_vm): Use
      scm_load_thunk_from_file.
      (make_boot_program): Adapt to use scm_bytecode_to_objcode with
      endianness arg.
    
    * module/Makefile.am (OBJCODE_LANG_SOURCES): Add (language objcode
      elf).
    * module/language/objcode/elf.scm: New module, embeds objcode in ELF.
    
    * module/language/bytecode/spec.scm (compile-objcode):
      (decompile-objcode): Use (target-endianness).
    
    * module/language/objcode/spec.scm: use (language objcode elf) for
      write-objcode.
    
    * module/scripts/disassemble.scm (disassemble):
    * module/system/repl/command.scm (disassemble-file): Use
      load-thunk-from-file.
    
    * module/system/vm/objcode.scm: Remove load-objcode and write-objcode.
    
    * test-suite/tests/asm-to-bytecode.test (test-target): Adapt to the new
      ELF world.

    add ELF loader
    
    * libguile/objcodes.h:
    * libguile/objcodes.c (scm_load_thunk_from_file)
      (scm_load_thunk_from_memory): New procedures.
    
    * libguile/elf.h: Import from glibc.  Not installed.
    
    * libguile/Makefile.am: Adapt for elf.h.
    
    * module/system/vm/objcode.scm: (load-thunk-from-file)
      (load-thunk-from-memory): New exports.
