During the Toybox port to NuttX, Claude noticed that changes in the
menuconfig weren't taking affect. This issue exists for a long time on
NuttX, in fact BayLibre's presentation from 2017 make jokes about our
building system not been reliable:

Stale archive members from $(AR)'s additive-only behavior can linger
after Kconfig toggles change which files provide a symbol, causing dead
weight or "multiple definition" link errors on incremental builds.
Fixed by splitting ARCHIVE into two macros: ARCHIVE keeps the original
additive behavior for apps/libapps.a, which many independent
subdirectories contribute to across a build, while the new
ARCHIVE_REBUILD deletes then archives for the far more common case
of a single Makefile building its own self-contained $(OBJS)
- all 39 such call sites now use it.

debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

Extend CONFIG_LIBCXXTOOLCHAIN support to all remaining platforms
in CMake builds by explicitly locating and linking libstdc++.a
from the toolchain. This prevents build failures caused by STL
header/library mismatches where toolchain headers are included
without the corresponding library.
* Adds nuttx_find_toolchain_lib() calls for all platforms.
* Aligns CMake behavior with Make build system.

Add validation to ensure allocated stack size does not exceed TLS_MAXSTACK when
CONFIG_TLS_ALIGNED is enabled, and verify proper stack alignment using STACK_ALIGN_MASK
across all architectures. This improves stack safety and prevents potential TLS overflow conditions.

After addrenv_switch(), the current running task (this_task) may change due to
deferred work execution. Update all architecture interrupt, syscall, and exit
handlers to re-fetch tcb = this_task() after addrenv_switch(). Ensures scheduler
and context operations use the correct TCB, preventing context corruption and
exceptions across SMP and memory-protected builds.

Make sure interrupt stack is colored before IRQ is enabled.
Currently, after calling irq_initialize in nx_start to
enable interrupts, there is still a period of execution
path before the interrupt stack is colored.

Many different architectures re-implemented the exact same code for
`up_*delay` because it was originally written as architecture dependent
code. Busy-waiting can be done regardless of architecture, so this
commit moves that duplicated implementation to a common file with weak
definitions so that individual architectures (see tc32) are still able
to override the definition if needed/desired.
Default implementation is not included if ARCH_TIMER is enabled, since
it is more accurate and provides its own weak definitions to override.

reason:
When entering an exception or interrupt, there are two sets of registers:
one is the "running regs", which we need to save,
and the other is the "ready to running regs", which we may soon use.
For consistency in logic, we can always store the "running regs" in the regs field of g_running_tasks,
otherwise it may lead to errors in the storage location of the "running regs."
When we need to access the "running regs," we should uniformly retrieve them from the regs field of g_running_tasks.
As the next step, we will rename the set_current_regs/up_current_regs functions
for each architecture to more appropriate names, solely for the purpose of identifying interrupts.
