Now that binutils-bare-metal, gcc-bare-metal and newlib-bare-metal packages
have been upgraded to support a list of architecture tuples, this patch
updates the toolchain-bare-metal-buildroot help text to describe the new
capability.
BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_ARCH is still backwards compatible with
its prior definition as defining a single tuple with this new definition
works exactly the same as before.

When gcc sees a linker option (-Wl,..) it executes the linker, leading to
confusing error messages if no source files are provided, E.G.:
% gcc
gcc: fatal error: no input files
compilation terminated.
% gcc -Wl,-z,now
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/12/../../../x86_64-linux-gnu/Scrt1.o: in function `_start':
(.text+0x17): undefined reference to `main'
collect2: error: ld returned 1 exit status
It is not really trivial to detect in the wrapper if linking will be done,
but we can at least check if any non-option arguments (E.G. source/object
files) are passed and skip the -Wl,.. options if not.
% ./host/bin/aarch64-linux-gcc
aarch64-linux-gcc.br_real: fatal error: no input files
compilation terminated.
With this fixed we no longer need the special case for --help -v from commit

The ARC toolchains from Synopsys unfortunately are not "pure"
toolchains: their sysroot no only contains the C library, but also
additional libraries, most notably libncurses and libexpat.
This confuses Buildroot, and causes build issues, and is anyway not a
supported situation. Until the toolchains get fixed, let's mark them
as broken.

The option BR2_TOOLCHAIN_EXTERNAL_SYNOPSYS_ARC just depends on
BR2_arc, but the choice of toolchains that appears once
BR2_TOOLCHAIN_EXTERNAL_SYNOPSYS_ARC=y only has choices for:
depends on BR2_arc750d || BR2_arc770d
and
depends on BR2_archs38_64mpy || BR2_archs38_full || \
BR2_archs4x_rel31 || BR2_archs4x
which means that if you have a BR2_archs38=y configuration, you end up
with no choice of toolchain, and the build fails with "No C library
selected". Fix this by making sure BR2_TOOLCHAIN_EXTERNAL_SYNOPSYS_ARC
can only be selected when an actual toolchain is available.

Note: this commit only deals with glibc and its internal libcrypt (or
lack thereof); other C libraries, musl and uClibc-NG, are not considered.
libcrypt from glibc has been deprecated for a long time, and it has now
been entirely dropped with glibc 2.39. Now, packages that need crypt(3)
features need to explicitly depend on the libxcrypt pacakge.
However, the set of files installed both by glibc and libxcrypt is not
empty:
glibc libxcrypt
/usr/include/crypt.h /usr/include/crypt.h
/usr/lib/libcrypt.a /usr/lib/libcrypt.a
/usr/lib/libcrypt.so /usr/lib/libcrypt.so
/lib/libcrypt.so.1
/lib/libcrypt-2.23.so
/usr/lib/libcrypt.so.2
The two libraries have different SO_NAME, so they do not conflict on the
library filename. However, the .so synlink is present in both, and thus
conflicts. The header and the static library also conflict.
So, the situation is that, with a glibc 2.39 or later, packages have to
use libxcrypt, which is a drop-in replacement. With glibc 2.38 or
earlier, they can use either.
Since we already bumped to glibc 2.39 for the internal toolchain, we
have already converted quite a few packages to use libxcrypt. That works
well with an internl toolchain, because glibc does not install the
conflicting files.
However, for external toolchains, we may very well end up in three
situations:
- a glibc 2.39 or later, without libcrypt
- a glibc 2.39 or later, without libcrypt, but with libxcrypt [0]
- a glibc 2.38 or earlier with libcrypt
In the first case, all is OK and we are in a situation similar to the
internal toolchain, but in the latter two cases, we end up with a
conflict.
We could introduce BR2_TOOLCHAIN_EXTERNAL_HAS_LIBCRYPT os something
along those lines, but this is going to be a bit complex on packages,
which would have to select LIBXCRYPT if GLIBC && !_HAS_LIBCRYPT.
So, to simplify things, we want to get the external toolchains into a
situation similar to the internal one, where libcrypt is not provided by
the toolchain; packages have to select libxcrypt for glibc toolchains,
without having to care whether this is an internal or external toolchain
or some more complex conditions.
So, we remove from staging whatever could be used to compile and link
with libcrypt. We however keep the SO_NAME file, if it exists, and we
also install it in target/, for those pre-built binaries that may be
linked with it [1]. The glibc SO_NAME has always been libcrypt.so.1, so
this is what we copy exactly, to avoid copying the libxcrypt one, which
is libcrypt.so.2.
[0] that could happen if a toolchain provider tried to be helpful and
suplies a toolchain with libxcrypt to be trasnparent to users, in which
case that would conflict with ours...
[1] if such a prebuilt binary (executable or library) is used with a
glibc 2.39 or later toolchain, it will obviously not work at all.
libxcrypt is supposed to be a drop-in replacement for glibc's libcrypt,
so we could look into symlinking libcrypt.so.1 to libcrypt.so.2. In a
later patch, maybe...

2024.02 Bootlin toolchains have been released, so let's update the
support in Buildroot. Notable changes:
- Bleeding edge toolchains now use binutils 2.42, and stable
toolchains use binutils 2.41. This fixes binutils bug 27597
for both.
- glibc has been updated to 2.39
- musl has been updated to 1.2.5, which brings 32-bit RISC-V
support. Due to this, 2 new toolchain variants are added: 32-bit
RISC-V stable, 32-bit RISC-V bleeding edge.
- Bleeding edge toolchains now use 5.15 kernel headers, and stable
toolchains now use 4.19 kernel headers
- Fortran support has been disabled on Microblaze, as the libgfortran
build at -O2 causes an internal compiler error.
All runtime tests are passing, except the ones for the new RISC-V
32-bit musl toolchain, for which Busybox fails to build due to an
interaction between musl-specific code in Busybox and musl. This issue
has been reported:
https://www.openwall.com/lists/musl/2024/03/03/2
The runtime tests are nevertheless included, with the hope that this
issue will reasonably quickly be resolved.

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
