New toolchains have been released, with the following changes:
- The bleeding-edge toolchains are based on gcc 13.2, binutils 2.41,
gdb 14.1, kernel headers 5.10, glibc 2.38, musl 1.2.4 or uclibc-ng
1.0.45.
- The stable toolchains are based on gcc 12.3, binutils 2.40, gdb
13.2, kernel headers 4.14, glibc 2.38, musl 1.2.4 or uclibc-ng
1.0.45.
- The glibc version is no longer affected by CVE-2023-4911
- The gdb build has been fixed to no longer rely on uninstalled
libbfd.so and libopcodes.so libraries
- The zlib library, which was incorrectly present in the toolchain
sysroot, is gone, fixing various build failures encountered with
2023.08 toolchains.
- There are now toolchains for m68k 68xxx based on uclibc and musl in
addition to glibc, which was already supported
The careful reviewer will notice that a number of
depends on !BR2_ARCH_NEEDS_GCC_AT_LEAST_14
are being added to the toolchains that use gcc 13.x, as per
a0d2a5cfec
("support/scripts/gen-bootlin-toolchains: generate
BR2_ARCH_NEEDS_GCC_AT_LEAST_X guard").
All 214 test cases were successfully run:

A new version of Bootlin toolchains, 2023.08, has been recently
released. Besides the usual updates of GCC, binutils, GDB, kernel
headers, and C libraries, support for AArch64 BE with musl has been
enabled, which explains why there are two new toolchains and two new
test cases.
All test cases where successfully tested:

Note that the sparcv8 uClibc toolchains are considered obsolete. They
are still available, but at some point we'll have to drop them from the
choice.

This commit is based on earlier work from Łukasz Stelmach
<l.stelmach@samsung.com> to add support for different page sizes on
ARM64.
In his initial submission, Łukasz took an approach similar to this
one, i.e make it ARM64-specific. Following the feedback on the mailing
list, his second version [1] tried to generalize the logic to
configure the page size between architectures. But the general
consensus during the review process was that there wasn't much to
generalize in the end.
So, this new iteration is back to a simpler approach:
* We have new options in Config.in.arm to configure the page
size. Only 4 KB and 64 KB are supported, because our testing in
Qemu and real hardware has not allowed to get a successful setup
for 16 KB pages. We can always re-add support for 16 KB later if
that is resolved.
* The logic to define the ARCH_TOOLCHAIN_WRAPPER_OPTS options is
moved from the ARC-specific file to arch/arch.mk, and extended to
cover ARM64.
* The appropriate logic in uclibc.mk and linux.mk is added to tweak
the relevant configuration options.
* A test case is added in the runtime test infrastructure to test
building and booting under Qemu a 64 KB configuration, with all 3 C
libraries.
For the regular configuration of 4 KB pages, this commit makes one
functional change: on ARM64, -Wl,-z,max-page-size=4096 is now passed in
the compiler flags of the wrapper.

Following the releases of 2021.11 Bootlin toolchains, this commit
represents the result of re-running the gen-bootlin-toolchains script.
The only part that isn't auto-generated are the contents of
Config.in.legacy, which account for the replacement of the RISC-V LP64
toolchain by RISC-V LP64D toolchains.

A recent update of flake8 in CI introduced a new check E741. It
basically checks that variables are at least 3 characters long. Up to
now, however, we have used shorter names in some places - all of them
turn out to be "l" for a line of text.
Replace all those "l" variables with "line".

The TestExternalToolchain() base class implement a test checking if
the ELF interpreter that is advertised by Busybox really exists in the
rootfs. Of course, this only makes sense with ELF toolchains. Until
now, only ELF toolchains were tested, but we are going to use
TestExternalToolchain() with non-ELF toolchains as well, so let's make
this conditional.

These tests simply build a system with musl and uclibc toolchains, and
boot them under qemu. It allows to minimally validate that our support
for musl/uclibc external toolchains is working. We already had some
tests covering glibc toolchains, so we can now easily test that all
three C libraries are supported.

validate that things are still working correctly with all of glibc,
uclibc and musl toolchains.
