RISC-V has no support for subword atomic operations; code currently
generates libatomic library calls.
This patch changes the default behavior to fast inline subword atomic
calls that do not require libatomic.

While improving access path analysis a typo happened. Now it can happen
that gcc misscompiles. The patch is fixing the issue. However, also
other gcc versions 10.2+ are affected. They also should be bumped or the
fix should be backported.

LTO object files will now be compressed using zstd.
Compressing debug sections with zstd will have to wait for GCC 13,
which adds support for -gz=zstd.
NOTE: wiping the ccache is strongly recommended, not doing so might
yield build error later on:
"lto1: internal compiler error: original not compressed with zstd"

This was apparently introduced to recreate the toolchain (wipe
staging_dir/toolchain*, but keep build_dir/toolchain*, followed by a
`make toolchain/compile`).
But it leaves leftovers and causes re-links to happen at src_install phase,
because of the changed paths, possibly adding yet another source of issues.
With the prior commits removing various hacks related to the "initial"
folder we can remove installing it twice altogether.
The recreated toolchain is exactly the same as before.

Instead of having two different ways to pass flags to the gcc build
process, add them as configure args, which is a reliable way to let
gcc pass them around to its various pieces.
Also add CXXFLAGS, since gcc started to use c++ for itself recently
(~10 years ago now).

Config evaluation require default with if to be put before the generic
default config with no condition. Putting the default config before any
conditional default results in always selecting the non conditional one.
This results in the version be hardcoded to gcc 12 even if gcc 11 is
selected in the Advanced build options.
Fix this by putting the gcc 12 default option as last after ANY
conditional default config.

This was build tested with all core packages on all targets
successfully.
Most packages from the feed are also building fine.
This was run tested on the following systems:
* lantiq/xrx200 musl
* pistachio/generic musl
* sunxi/cortexa53 musl
* x86/64 musl
* x86/64 glibc
* armvirt/64 musl
The size of the images stays more or less the same for MIPS BE and
aarch64. I haven't tested other architectures.
With GCC 11 I got these sizes for lantiq/xrx200:
7,219,848 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin
7,472,208 openwrt-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin
With GCC 12 I got these sizes for lantiq/xrx200:
7,217,355 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin
7,406,674 openwrt-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin
The sysupgrade image is probably padded. The initramfs image is 0.03% smaller.
With GCC 11 I got these sizes for armvirt/64:
4,143,943 openwrt-armvirt-64-default-rootfs.tar.gz
10,887,176 openwrt-armvirt-64-Image
24,911,880 openwrt-armvirt-64-Image-initramfs

Every minor version bump of a major version will result in a huge patch
diff because of the moving of all the patches from version e.g. 11.2.0 to
11.3.0. This commit only use the major version for the patch folders to
differentiate between the different gcc versions. This will significantly
improve the reviewing of the smaller version bump patches and help to see
what really changed in a minor version bump.

At configuration time, gcc assumes that ppc64be targets use the ELFv1
ABI, and ppc64le targets use the ELFv2 ABI. However, musl libc does not
support the ELFv1 ABI on ppc64 at all, regardless of the endianness.
Therefore, when building for a ppc64 arch and with musl libc, instruct
gcc to use the ELFv2 ABI.

GCC 5.1 changed the std::string ABI in order to properly support C++11.
For compatibility with libraries compiled with the older ABI, that is,
linking between old-abi.so and new-abi.bin, both ABIs are enabled. In
terms of OpenWrt, all packages are compiled with the same toolchain,
which means these issues do not need to be handled.
Most importantly, this results in a significant size reduction of
libstdpp:
Before:
450794 bytes
After:
327752 bytes

Removes the standalone implementation of stack smashing protection
in gcc's libssp in favour of the native implementation available
in glibc and uclibc. Musl libc already uses its native ssp, so this
patch does not affect musl-based toolchains.
Stack smashing protection configuration options are now uniform
across all supported libc variants.
This also makes kernel-level stack smashing protection available
for x86_64 and i386 builds using non-musl libc.
