binutils/binutils-skip-rpaths.patch
Michael Matz afea8f6d7a Accepting request 671129 from home:marxin:branches:devel:gcc 
- Update to binutils 2.32:
    * The binutils now support for the C-SKY processor series.
    * The x86 assembler now supports a -mvexwig=[0|1] option to control
      encoding of VEX.W-ignored (WIG) VEX instructions.
      It also has a new -mx86-used-note=[yes|no] option to generate (or
      not) x86 GNU property notes.  
    * The MIPS assembler now supports the Loongson EXTensions R2 (EXT2),
      the Loongson EXTensions (EXT) instructions, the Loongson Content
      Address Memory (CAM) ASE and the Loongson MultiMedia extensions
      Instructions (MMI) ASE.
    * The addr2line, c++filt, nm and objdump tools now have a default
      limit on the maximum amount of recursion that is allowed whilst
      demangling strings.  This limit can be disabled if necessary.
    * Objdump's --disassemble option can now take a parameter,
      specifying the starting symbol for disassembly.  Disassembly will
      continue from this symbol up to the next symbol or the end of the
      function.
    * The BFD linker will now report property change in linker map file
      when merging GNU properties.
    * The BFD linker's -t option now doesn't report members within
      archives, unless -t is given twice.  This makes it more useful
      when generating a list of files that should be packaged for a
      linker bug report.
    * The GOLD linker has improved warning messages for relocations that
      refer to discarded sections.
- Remove binutils-2.31-branch.diff.gz, fix-pr23919-[123].diff,
  gold-depend-on-opcodes.diff and s390-relro.diff.
- Refresh binutils-skip-rpaths.patch, s390-biarch.diff, cross-avr-size.patch
  and binutils-revert-plt32-in-branches.diff.
