This will be needed to work around a GCC bug affecting python3. The
bug is reported at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121567.
This bug affects GCC at least since 6.x, but we couldn't test earlier
versions, so we simply assume all GCC versions are affected. Even GCC
15.x is still affected, as reported to upstream GCC.

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.

similar to previous problems with nios2 and not-available atomic ints
the build for Boost.Atomics also fails for ARC Targets which don't
have the ATOMICS_EXT flag set.
according to [0] "Boost.Atomic has a hard requirement of the native
atomic operations on bytes". The same tests mentioned there fail for
ARC without the atomic extension.
Disable BR2_TOOLCHAIN_SUPPORTS_ALWAYS_LOCKFREE_ATOMIC_INTS for BR2_arc
without BR2_ARC_ATOMIC_EXT.

As suggested by Thomas Petazzoni in [1], add a comment on
BR2_TOOLCHAIN_HAS_UCONTEXT to specify that this boolean will be set to
true only when a toolchain provides a full featured ucontext
implementation with ucontext_t and {get,make,set}context. As a result,
drop its selection from BR2_TOOLCHAIN_USES_MUSL to fix the following
musl build failure on php:

This patch adds a new virtual package for adding a bare-metal
toolchain to Buildroot. For now, it depends on nothing, so it will not
actually build anything, but it defines some options that will be
needed by the various packages that will be part of this toolchain
build process.
