41f7f821f6 Toolchain+Ports: Use ftpmirror.gnu.org for faster downloads
This service automatically redirects to a mirror that's geographically
closer, which should make downloading the tarballs faster. The GNU
project recommends this instead of bombarding their top-level downloads
site.

6bcd73a2ff Toolchain: Disable libstdc++ PCH compilation
These are not useful for us, and unnecessarily waste time when building
the toolchain. Even if we used libstdc++ more heavily, our use of
uncommon, PCH-affecting flags and our frequent LibC header changes would
make these ineligible for use anyways.

58da4c93fb Toolchain+CI: Remove cache handling logic from BuildIt.sh
Instead of manually compressing/decompressing a toolchain tarball if
`TRY_USE_LOCAL_TOOLCHAIN` is set, let's use the cache action's automatic
built-in compression (which is zstd, I believe).

02fe3feb71 Toolchain: Enable RELRO support for AArch64
The BFD linker requires the `COMMONPAGESIZE` emulation parameter to be
set in order to enable RELRO support for AArch64. As we are adding a
custom `emulparams` file anyways, let's also tell LD that our ELF
interpreter is called `/usr/lib/Loader.so`.

This commit also removes some vestigial references to i686 SerenityOS.
The one in `gas/configure.tgt` is still needed, as it also handles
x86_64.

07918b79b7 Toolchain+Ports: Update GCC to 13.1.0
This is a mostly straight-forward rebase of our patches on top of
13.1.0. The spec files needed a change, as GCC no longer supports STABS
debug information, but we were building GCC with support for it.

Highlights of this release include static `operator()`, The Equality
Operator You Are Looking For and extended `constexpr` support.

4c2ad70066 Toolchain: Use ninja to bootstrap CMake
For some reason (for me) on Ubuntu 22.04 the standard make generator
fails:

  ---------------------------------------------
  CMake has bootstrapped.  Now run gmake.
  make: make: Permission denied
  make: *** [Makefile:166: all] Error 127

This seems to be because Source/kwsys/CMakeFiles/cmsys.dir/depend is
missing or not generated. Using ninja works fine though, and as it is
already the default for Serenity proper, it seems reasonable to switch
it here too.

a7f61a15af Toolchain: Fix self-built QEMU crashing on startup on macOS
If the SDL libraries are present on the system, QEMU will attempt to use
that for rendering the UI. This causes a crash when the AArch64 port
starts up with the following message:

> NSWindow drag regions should only be invalidated on the Main Thread!

Fix this by explicitly disabling SDL support.

1cc095c5ab Toolchain+Ports: Consolidate version information for QEMU
This consolidates version information, archive's download location,
filename and SHA256 checksum into version.sh. This file is then sourced
from the port script and toolchain build script.

The version.sh script contains the following variables:
- QEMU_VERSION           - Version number
- QEMU_ARCHIVE           - Filename
- QEMU_ARCHIVE_URL       - Full url to download location
- QEMU_ARCHIVE_SHA256SUM - The SHA256 checksum

5ca1bd55a0 Toolchain: Move GDB build to a separate script
Target GDB is only used for debugging the kernel, which is not relevant
to most people. Starting with 924758c6f8, GDB would always be built
as part of the toolchain if the user didn't have it installed. This is
unnecessary.

This commit adds a separate script for building GDB, which the user
needs to explicitly invoke. A message is added to Meta/debug-kernel.sh
which alerts the user to this fact.

924758c6f8 Toolchain+Meta: Support kernel debugging with host AArch64 GDB
Previously, we would unconditionally build GDB from source for the
AArch64 toolchain. This commit makes it possible to use the system's
`gdb` binary if it supports the architecture, or `aarch64-elf-gdb` if
such a package is installed.

An `aarch64-elf-gdb` package will be available through Homebrew once
this PR is merged: https://github.com/Homebrew/homebrew-core/pull/127323

invalid sed command to be created, breaking both of these scripts.

7eccacf418 Toolchain: Ensure aarch64 libgcc_s.so.1 includes DT_SONAME tag
Without this tag, executables that link libgcc_s.so.1, which is every
executable, end up with the host path to libgcc_s.so.1 as the path for
the dynamic dependency (DT_NEEDED) of the executable. By making sure
that the libgcc_s.so.1 shared object includes the DT_SONAME tag, the
path to libgcc_s.so.1 dynamic dependency will only contain the basename,
instead of the absolute host path.

similar to what we do for gdb, llvm, gcc, and binutils later.

bc2ebcadc0 Everywhere: Require version >= 12 for GCC host compiler
So far we've gotten away with using GCC 11 for Lagom and to compile the
toolchain, but via #15795 we discovered a compiler bug that has been
fixed in the latest version but would error the build with CI's GCC 11.
Time for an upgrade :^)

We already use ubuntu-22.04 images in most places, so this is pretty
straightforward. The only exception is Idan's self-hosted runner, which
uses Ubuntu Focal. LibJS should build fine with GCC 11, still.

Neither are we changing any of our documentation files, nor do we need

With macOS potentially removing makeinfo from the default Xcode lineup,
SerenityOS not being able to install it at all currently due to a lack
of perl, and it otherwise just being a dependency that has to be
installed to make the build system happy, lets just stub it out.

29fefe2d3e Toolchain: Explicitly install llvm-config and FileCheck
Also disable the "toolchain only build" to ensure we install llvm
headers for when we want to build host tools that link against llvm.

01b31d9858 Toolchain+Ports: Update LLVM to 14.0.1
Besides a version bump, the following changes have been made to our
toolchain infrastructure:
- LLVM/Clang is now built with -march=native if the host compiler
  supports it. An exception to this is CI, as the toolchain cache is
  shared among many different machines there.
- The LLVM tarball is not re-extracted if the hash of the applied
  patches doesn't differ.
- The patches have been split up into atomic chunks.
- Port-specific patches have been integrated into the main patches,
  which will aid in the work towards self-hosting.
- <sysroot>/usr/local/lib is now appended to the linker's search path by
  default.
- --pack-dyn-relocs=relr is appended to the linker command line by
  default, meaning ports take advantage of RELR relocations without any
  patches or additional compiler flags.

The formatting of LLVM port's package.sh has been bothering me, so I
also indented the arguments to the CMake invocation.

97c0a8c063 Toolchain: Move nix script from Documentation into Toolchain
Moves the nix script to setup the build environment from Documentation
into the Toolchain as a callable script.  I also modified the script
to accept a "pkgs" argument to make it easy to override the nixpkgs
version from the command-line when calling the script.
