In the internal toolchain backend, we have a choice..endchoice block
to allow the user to select the C library, between glibc, uClibc and
musl.
However, there are situations were no C library at all is
supported. In this case, the choice does not appear, and does not
allow to see the Config.in comments that are within the
choice..endchoice block and that may explain why no C library is
available.
For example, on RISC-V 32-bit, the only C library supported is glibc,
and the minimum kernel header version required by glibc on this
architecture is 5.4.0. In a future commit, we are going to add this
dependency on glibc (to fix build issues on configurations that have
headers < 5.4.0). But since glibc is the only supported C library on
RISC-V 32-bit, it means that the choice..endchoice for the C library
contains no entry, preventing from seeing the Config.in comment.
To address this issue, this commit adds a "dummy"
BR2_TOOLCHAIN_BUILDROOT_NONE option that shows up in the
choice..endchoice only when no C library is available. Thanks to this,
the choice..endchoice is never empty, and the Config.in comments can
be seen.
If the user keeps BR2_TOOLCHAIN_BUILDROOT_NONE selected, then the
build will anyway abort early because package/Makefile.in has a check
to verify that a C library is selected, and aborts the build if not.
Some could say that the problem should be resolved by instead
preventing the selection of headers < 5.4.0 on RISC-V 32-bit, but that
is difficult to do as the user can choose a custom header version, or
simply specific that (s)he wants to use the headers of the kernel
being built. In those situations, it's difficult to prevent selecting
headers < 5.4.0.
Prevent random configurations from triggering a build failure in our
autobuilders, by excluding that symbol from accepted configuration.

It should be noted that openssl3 has added OPENSSL_DEV_NO_ATOMICS but
"this is intended for internal development only, to check the
refcounting is properly coded. It should never become a configuration
option, hence the name of the macro.":
503d4745a1
Atomics are not available in Buildroot if:
- architecture is 32 bit and something other than ARM or xtensa, and
- GCC < 4.8 or no threads or FLAT.
The nothreads case can theoretically happen in many different
situations, but in practice nobody disables threads. So the only
interesting case is the FLAT case. Since ARM and RISC-V 64 both have
atomics intrinsics, that leaves just m68k NOMMU as FLAT. So this is
truly a corner case.
The proper solution would be to patch GCC to also provide libatomic in
those cases.
- For nothreads, atomics are in fact not needed, so libatomic can simply
be implemented as stubs.
- For FLAT, it's probably just a matter of having a match to uclinux in
libatomic/configure.tgt.
Again, though, this happens only in such niche cases that it's not worth
working on it.

In case of an unexpected error, we currently only print the exception as
an str(). For example, the recent issue with the glibc version check
only reported:
TypeError: cannot use a string pattern on a bytes-like object
That does not help in fixing the issue; the exception text is also not
usually very user-friendly either anyway.
We change the reporting to print the traceback, which in the glibc
version check mentioned above, the error is reported as:
Traceback (most recent call last):

The support for this architecture has been removed from the upstream
Linux kernel, as of commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=aec499c75cf8e0b599be4d559e6922b613085f8f
Which states:
The nds32 architecture, also known as AndeStar V3, is a custom
32-bit RISC target designed by Andes Technologies. Support was added
to the kernel in 2016 as the replacement RISC-V based V5 processors
were already announced, and maintained by (current or former) Andes
employees.
As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.
There has also been little to no maintenance done in Buildroot for
this architecture in recent times, so let's follow the Linux kernel
community decision and drop support for this CPU architecture.

Until commit "arch/Config.in.sh: fixup MMU selection" in this series,
SH2A could either be used with BR2_USE_MMU disabled or BR2_USE_MMU
enabled.
The later made absolutely no sense, since SH2A does not have a MMU:
MMU support was introduced starting from SH3 according to
https://en.wikipedia.org/wiki/SuperH#SH-3
Also, since commit 22d5501e03 ("arch:
tidy up binary formats config"), which was merged in Buildroot
2015.05, the architecture tuple used when BR2_sh2a=y and BR2_USE_MMU
disabled is sh2a-buildroot-uclinux-uclibc, and this was already
unsupported back in the days of Buildroot 2015.08 and binutils 2.24,
causing the build to fail with:
*** BFD does not support target sh2a-buildroot-uclinux-uclibc.
just like it fails to build today with recent version of binutils.
So, this has been broken since 2015.08, and nobody complained. SH2A is
seldom used, so it's time to kill it.
It is worth mentioning that there had been an attempt at resurrecting
SH2 support around 2015 (see https://lwn.net/Articles/647636/) as part
of the J2 core. This effort led to the addition of FDPIC support for
SH2A in the musl C library (and therefore proper ELF binaries, with
shared libraries), but that was never supported in Buildroot. Now that
the J2 project is essentially dead, there is no reason to bother with
this.

Currently we only test a limited set of toolchains that are mostly
prebuilt, add a flag to allow using randconfig for randomizing
additional toolchain settings instead of randpackageconfig.
To avoid invalid configs we need to add additional config validation
filtering and fixups. Although the loop around 'make randconfig'
attempts does make sure we eventually end up with a valid configuration,
there is a bias towards e.g. disabling the kernel. It would be possible
to e.g. always force BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y, but
that removes the possibility for a toolchains-csv config to add a valid
custom defconfig. (Note that currently this isn't possible anyway since
'make randpackageconfig' is used if a toolchains-csv is provided, but
eventually we want to use 'make randconfig' also if a toolchains-csv is
provided.)

genrandconfig is used by the Buildroot autobuilders to generate
semi-random configurations that we build test. As part of this, we use
"make randpackageconfig" to randomize the selection of packages,
together with a KCONFIG_PROBABILITY value, which indicates the
probabibility for each option to be enabled. This probability is
itself randomized, between 1% and 30% for every build.
However, with our increasing number of packages (over 2900), when we
use a 30% probability for options to be enabled, it means a *lot* of
options are enabled, causing very large configurations to be
tested. These configurations are not very realistic, and they take
ages to build on our autobuilders: we have builds that take 4, 5 or
even 7 hours to build.
In order to test a larger number of configurations and therefore a
larger variety of configurations, this commit reduces the maximum
probability to 20%.
