Update cross/avr-binutils to 2.30

Date: 	Sat, 27 Jan 2018 16:33:36 +0000
  This release contains numerous bug fixes, and also the
  following new features:

  In the assembler:
      * Add support for location views in DWARF debug line information.

  In the BFD linker:
      * Add -z separate-code to generate separate code PT_LOAD segment.

    * Add "-z undefs" command line option as the inverse of the \ 
"-z defs" option.

    * Add -z globalaudit command line option to force audit libraries to be run
      for every dynamic object loaded by an executable - provided that the loader
      supports this functionality.

    * Tighten linker script grammar around file name
      specifiers to prevent the use of SORT_BY_ALIGNMENT and
      SORT_BY_INIT_PRIORITY on filenames.  These would
      previously be accepted but had no effect.

    * The EXCLUDE_FILE directive can now be placed within any
      SORT_* directive within input section lists.

  In the GOLD linker:
    * Add support for .MIPS.options sections (MIPS only).

    * Add support for compound relocations (MIPS only).

    * Add --emit-stub-syms, --no-tls-optimize, --tls-get-addr-optimize
      options (PowerPC only).

    * Add -z text-unlikely-segment option.

    * Add plugin support for adding new input files
      (LDPT_REGISTER_NEW_INPUT_HOOK).

  In the utilities:
    * Add --debug-dump=links option to readelf and
      --dwarf=links option to objdump which displays the
      contents of any .gnu_debuglink or .gnu_debugaltlink
      sections.

    * Add a --debug-dump=follow-links option to readelf and a
      --dwarf=follow-links option to objdump which causes  indirect
      links into separate debug info files to be followed when
      dumping other DWARF sections.
