are copied from the original inferior to the new one. All modifications to
the environment variables done using the 'set environment' or 'unset
environment' commands are also copied to the new inferior.
Various new commands have been introduced

Switch checksums from MD5 to BLAKE2
Historically, the MD5 checksums in our LFS files serve as a protection against broken downloads, or accidentally corrupted source files. While the sources are nowadays downloaded via HTTPS, it make sense to beef up integrity protection for them, since transparently intercepting TLS is believed to be feasible for more powerful actors, and the state of the public PKI ecosystem is clearly not helping. Therefore, this patch switches from MD5 to BLAKE2, updating all LFS files as well as make.sh to deal with this checksum algorithm. BLAKE2 is notably faster (and more secure) than SHA2, so the performance penalty introduced by this patch is negligible, if noticeable at all. In preparation of this patch, the toolchain files currently used have been supplied with BLAKE2 checksums as well on https://source.ipfire.org/.

gdb: Update to version 11.1
- Update from 10.2 to 11.1
- Update of rootfile
- Changelog
Version 11.1 of GDB includes the following changes and enhancements:
Support for ARM Symbian (arm*-*-symbianelf*) has been removed.
Building GDB now requires GMP (The GNU Multiple Precision Arithmetic Library).
New command-line options "--early-init-command" (or "-eix") and
"--early-init-eval-command" (or "-eiex")
GDB/MI Changes:
New --qualified option for the '-break-insert' and '-dprintf-insert' commands.
New --force-condition option for the '-break-insert' and '-dprintf-insert' commands.
New --force option for the '-break-condition' command.
The '-file-list-exec-source-files' now accepts an optional regular expression to
filter the source files included in the result.
The results from '-file-list-exec-source-files' now include a 'debug-fully-read'
field to indicate if the corresponding source's debugging information has been
partially read (false) or has been fully read (true).
TUI Improvements:
Mouse actions are now supported. The mouse wheel scrolls the appropriate window.
Key combinations that do not have a specific action on the focused window are now
passed to GDB.
Python enhancements:
Inferior objects now contain a read-only 'connection_num' attribute that gives the
connection number as seen in 'info connections' and 'info inferiors'.
New method gdb.Frame.level() which returns the stack level of the frame object.
New method gdb.PendingFrame.level() which returns the stack level of the frame
object.
When hitting a catchpoint, the Python API will now emit a gdb.BreakpointEvent
rather than a gdb.StopEvent. The gdb.Breakpoint attached to the event will have
type BP_CATCHPOINT.
Python TUI windows can now receive mouse click events. If the Window object
implements the click method, it is called for each mouse click event in this
window.
New setting "python ignore-environment on|off"; if "on", causes GDB's builtin
Python to ignore any environment variable that would otherwise affect how Python
behaves (needs to be set during "early initialization" (see above).
New setting "python dont-write-bytecode auto|on|off".
Guile API enhancements:
Improved support for rvalue reference values.
New procedures for obtaining value variants: value-reference-value,
value-rvalue-reference-value and value-const-value.
New "qMemTags" and "QMemTags" remote protocol packets (associated with Memory Tagging).
GDB will now look for the .gdbinit file in a config directory before looking for
~/.gdbinit. The file is searched for in the following locations: $XDG_CONFIG_HOME/gdb/gdbinit, $HOME/.config/gdb/gdbinit, $HOME/.gdbinit. On Apple hosts the search order is instead: $HOME/Library/Preferences/gdb/gdbinit, $HOME/.gdbinit.
The "break [...] if CONDITION" command no longer returns an error when the condition
is invalid at one or more locations. Instead, if the condition is valid at one or
more locations, the locations where the condition is not valid are disabled.
The behavior of the "condition" command is changed to match the new behavior of the
"break" command.
Support for general memory tagging functionality (currently limited to AArch64 MTE)
Core file debugging now supported for x86_64 Cygwin programs.
New "org.gnu.gdb.riscv.vector" feature for RISC-V targets.
GDB now supports fixed point types which are described in DWARF as base types with a
fixed-point encoding. Additionally, support for the DW_AT_GNU_numerator and
DW_AT_GNU_denominator has also been added.
Miscellaneous:
New "startup-quietly on|off" setting; when "on", behaves the same as passing the
"-silent" option on the command line.
New "print type hex on|off" setting; when 'on', the 'ptype' command uses
hexadecimal notation to print sizes and offsets of struct members. When 'off',
decimal notation is used.
The "inferior" command, when run without argument, prints information about the
current inferior.
The "ptype" command now supports "/x" and "/d", affecting the base used to print
sizes and offsets.
The output of the "info source" has been restructured.
New "style version foreground | background | intensity" commands to control the
styling of the GDB version number.
Various debug and maintenance commands (mostly useful for the GDB developers)
