binutils: update to 2.38.

This release contains numerous bug fixes and improvements, along with
the following new features:

Assembler:
  General:
    * Add support for the LoongArch architecture.

    * Add an option to control how multibyte characters are handled in
      the assembler.  Using the option warnings can be generated when
      such characters are encountered in symbol names, or anywhere in
      the input source file(s).

  AArch64 and ARM:
    * Add support for more system registers.
    * Add support for Scalable Matrix Extension.
    * Add support for Cortex-R52+, Cortex-A510, Cortex-A710,
      Cortex-X2, Cortex-A710 cores.
    * Add support for 'v8.7-a', 'v8.8-a', 'v9-a', 'v9.1-a',
      'armv9.2-a' and 'armv9.3-a' architecture extensions.

  X86:
    * Add a command-line option to encode aligned vector move as
      unaligned vector move.
    * Add support for Intel AVX512_FP16 instructions.
    * The outputs of .ds.x directive and .tfloat directive with hex
      input have been reduced from 12 bytes to 10 bytes to match the
      output of .tfloat directive.

Linker:
  * Add support for the LoongArch architecture.

  * Add -z pack-relative-relocs/-z no pack-relative-relocs to x86 ELF
   linker to pack relative relocations in the DT_RELR section.

  * Add -z indirect-extern-access/-z noindirect-extern-access to x86
    ELF linker to control canonical function pointers and copy
    relocation.

Other Binary Tools:

  * elfedit: Add --output-abiversion option to update ABIVERSION.

  * Tools which display symbols or strings (readelf, strings, nm,
    objdump) have a new command line option which controls how unicode
    characters are handled.  By default they are treated as normal for
    the tool.  Using --unicode=locale will display them according to
    the current locale.  Using --unicode=hex will display them as hex
    byte values, whilst --unicode=escape will display them as escape
    sequences.  In addition using --unicode=highlight will display
    them as unicode escape sequences highlighted in red (if supported
    by the output device).

  * readelf -r dumps RELR relative relocations now.

  * Support for efi-app-aarch64, efi-rtdrv-aarch64 and
    efi-bsdrv-aarch64 has been added to objcopy in order to enable
    UEFI development using binutils.

  * ar: Add --thin for creating thin archives. -T is a deprecated
    alias without diagnostics. In many ar implementations -T has a
    different meaning, as specified by X/Open System Interface.
