Log Message:
Update to 2.30

Changelog:
  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.
