Changes in 2.26:

* Add option to objcopy to insert new symbols into a file:
  --add-symbol <name>=[<section>:]<value>[,<flags>]

* Add support for the ARC EM/HS, and ARC600/700 architectures.

* Extend objcopy --compress-debug-sections option to support
  --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
  targets.

* Add --update-section option to objcopy.

* Add --output-separator option to strings.

* Add a configure option --enable-compressed-debug-sections={all,gas} to
  decide whether DWARF debug sections should be compressed by default.

* Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
  assembler support for Argonaut RISC architectures.

* Add --fix-stm32l4xx-629360 to the ARM linker to enable a link-time
  workaround for a bug in the bus matrix / memory controller for some of
  the STM32 Cortex-M4 based products (STM32L4xx)

* Add a configure option --enable-compressed-debug-sections={all,ld} to
  decide whether DWARF debug sections should be compressed by default.

* Add support for the ARC EM/HS, and ARC600/700 architectures.

* Experimental support for linker garbage collection (--gc-sections)
  has been enabled for COFF and PE based targets.

* New command line option for ELF targets to compress DWARF debug
  sections, --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi].

* New command line option, --orphan-handling=[place|warn|error|discard], to
  adjust how orphan sections are handled.  The default is 'place' which gives
  the current behaviour, 'warn' and 'error' issue a warning or error
  respectively when orphan sections are found, and 'discard' will discard all
  orphan sections.

* Add support for LLVM plugin.

* Add --print-memory-usage option to report memory blocks usage.

* Add --require-defined option, it's like --undefined except the new symbol
  must be defined by the end of the link.
