gdb: Upgrade to 13.1

gdb: Upgrade to 13.1

Add patch to fix typo for build on musl

GDB 13.1 includes the following changes and enhancements:

* Support for the following new targets has been added in both
  GDB and GDBserver:

  ** GNU/Linux/LoongArch (gdbserver) loongarch*-*-linux*

  ** GNU/Linux/CSKY (gdbserver) csky*-*linux*

* The Windows native target now supports target async.

* FreeBSD:

  ** Arm and AArch64: Support for Thread Local Storage (TLS) variables

  ** Hardware watchpoint support on AArch64 FreeBSD

* Floating-point support has now been added on LoongArch GNU/Linux.

* New commands:

 ** set print nibbles [on|off]
    show print nibbles

    This controls whether the 'print/t' command will display binary values
    in groups of four bits, known as "nibbles".  The default is 'off'.

 ** Various styling-related commands. See the gdb/NEWS file for more
    details (see link at the bottom).

 ** Various maintenance commands.  These are normally aimed at GDB
    experts or developers. See the gdb/NEWS file for more details
    (see link at the bottom).

* Python API improvements:

 ** New Python API for instruction disassembly.
    The new attribute 'locations' of gdb.Breakpoint returns a list of
    gdb.BreakpointLocation objects specifying the locations where the
    breakpoint is inserted into the debuggee.

 ** New Python type gdb.BreakpointLocation.

 ** New function gdb.format_address(ADDRESS, PROGSPACE, ARCHITECTURE)
    that formats ADDRESS as 'address <symbol+offset>'

 ** New function gdb.current_language that returns the name of the
    current language.  Unlike gdb.parameter('language'), this will
    never return 'auto'.

 ** New function gdb.print_options that returns a dictionary of the
    prevailing print options, in the form accepted by gdb.Value.format_string.

 ** New method gdb.Frame.language that returns the name of the
    frame's language.

 ** gdb.Value.format_string now uses the format provided by 'print',
    if it is called during a 'print' or other similar operation.

 ** gdb.Value.format_string now accepts the 'summary' keyword.  This
    can be used to request a shorter representation of a value, the
    way that 'set print frame-arguments scalars' does.

 ** The gdb.register_window_type method now restricts the set of
    acceptable window names.  The first character of a window's name
    must start with a character in the set [a-zA-Z], every subsequent
    character of a window's name must be in the set [-_.a-zA-Z0-9].

* GDB/MI changes:

  ** MI version 1 is deprecated, and will be removed in GDB 14.

  ** The async record stating the stopped reason 'breakpoint-hit' now
     contains an optional field locno.

* Miscellaneous improvements:

  ** gdb now supports zstd compressed debug sections (ELFCOMPRESS_ZSTD) for ELF.

  ** New convenience variable $_inferior_thread_count contains the number
     of live threads in the current inferior.

  ** New convenience variables $_hit_bpnum and $_hit_locno, set to
     the breakpoint number and the breakpoint location number of
     the breakpoint last hit.

  ** The "info breakpoints" now displays enabled breakpoint locations
     of disabled breakpoints as in the "y-" state.

  ** The format of 'disassemble /r' and 'record instruction-history /r'
     has changed to match the layout of GNU objdump when disassembling.

     A new format "/b" has been introduce to provide the old behavior
     of "/r".

  ** The TUI no longer styles the source and assembly code highlighted
     by the current position indicator by default. You can however
     re-enable styling using the new "set style tui-current-position"
     command.

  ** It is now possible to use the "document" command to document
     user-defined commands.

  ** Support for memory tag data for AArch64 MTE.

* Support Removal notices:

  ** DBX mode has been removed.

  ** Support for building against Python version 2 has been removed.
     It is now only possible to build GDB against Python 3.

  ** Support for the following commands has been removed:

     set debug aix-solib on|off
     show debug aix-solib
     set debug solib-frv on|off
     show debug solib-frv

     Use the "set/show debug solib" commands instead.
