This is necessary to build on MacOS. As discussed in #15530, Serenity
no longer appears to build on MacOS Ventura. This attempts to fix that
by enforcing it at the command level.
QEMU 7.1 was released on August 30th.
Release Notes: https://wiki.qemu.org/ChangeLog/7.1
The patch 'Toolchain/Patches/qemu-cf-protection-none.patch' (or similar)
has been upstreamed so it can be safely removed.
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.
I originally missed this while handling the upgrade to LLVM 15 (as it
only affects the on-serenity port), so the patch gets to be here with a
bit of a delay.

There was a typo in one of the spec files which resulted in us not
building softfp support for libgcc. Additionally we were missing flags
to build libgcc_s. This patch also makes sure we're not trying to
link against crtbeginS.o and crtendS.o. This is part of a larger effort
to at least get the userland to build at all.
Neither are we changing any of our documentation files, nor do we need
any of the documentation that is likely being built.
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.
Nix (nixpkgs) have updated a while back how the e2fsprogs derivation
works and now fuse2fs wasnt being installed with it. It is now needed to
add a new derivation (package) to the dependency list: "fuse2fs". This
fixes the Meta/serenity.sh script not finding the fuse2fs binary for
rootless image building :^)
This is a preparation to check if our users find noticeable bugs in the
x86-64 target, before we can decide if we want to remove the i686 target
for good.
This keeps us from accidentally building toolchains that don't make it
through a clean build if we build them using a populated sysroot, as it
would otherwise detect libpthread and friends and try to pull them in
while LibC is not yet built.
Following the pattern for qemu, mold, and clang, we should install the
host ruby required to build the ruby port into its own install tree
rather than forcing it into the GNU compiler's bindir.
Following the pattern for qemu, mold, and clang, we should install the
host python required to build the python port into its own install tree
rather than forcing it into the GNU compiler's bindir.
Now that the lower pages can be unmapped and more of the virtual
address range is available to us, we can actually use the default
mapping address of x86_64 again.
This reverts commit 292398b585.
This shouldn't cause any breaking changes, so a toolchain rebuild is not
required.
As per Hendiadyoin's request, math errno is disabled by default, which
should enable some extra compiler optimizations in LibGL and LibSoftGPU
code that uses math functions heavily.

This release brings support for various C++23 constructs like `if
consteval` and multidimensional subscript operators. Vectorization is
now enabled for O2 too, and `-ftrivial-auto-var-init` has been added
which can help us find and prevent security issues coming from
uninitialized variables.
Toolchain/Patches/gcc.patch is now significanly smaller as some unused,
autoconf-generated code has been removed.
