The existing first-order LCG (seed = 470001 * seed % 999563) has several
quality problems:
- Output range limited to [1, 999562] (~20 bits) instead of full 32-bit
- Lower bits have very short periods (8-bit period = 1, 16-bit = 105)
- Overall period only ~1M, far too short for many applications
- Causes mbedtls_rsa_gen_key to loop forever when rand() consumption
aligns with the cycle length (issue #16760)
Replace the entire order-based LCG implementation (CONFIG_LIBC_RAND_ORDER
0-3) with Marsaglia's xorshift32:
- Full 32-bit output range
- Period 2^32 - 1 (~4.29 billion)
- Fast: just three XOR/shift operations
- No floating-point math needed
- No CONFIG_LIBC_RAND_ORDER configuration required
Remove the CONFIG_LIBC_RAND_ORDER Kconfig option and clean up all
defconfig references (12 boards) and related comments.

The default sim:nsh config has no RTC, causing NSH_DISABLE_DATE to be
auto-enabled (default: DEFAULT_SMALL || !RTC). This means the date
command is not compiled in, and the system time defaults to a hardcoded
value instead of syncing with the host.
Enable CONFIG_RTC, CONFIG_RTC_DRIVER, and CONFIG_RTC_ARCH in the
sim:nsh defconfig so the date command is available and shows the
correct host time out of the box.

instead of an Apple Darwin Rust target. This keeps Rust cfg values aligned
with NuttX while producing Mach-O objects required by the simulator link.
Also align sim host handling for aarch64 Linux by detecting `aarch64` as
`HOST_ARM64` and avoiding x86-specific `-mcmodel` and `-no-pie` options

Resolve PLT entries at load time on Linux hosts so early host calls do not enter the lazy binder with simulated interrupts masked.
On Ubuntu 20 with GCC 9, the sim:nsh binary linked successfully after the -no-pie fix but crashed very early at runtime inside _dl_fixup / _dl_runtime_resolve_xsavec when up_irq_save() triggered a first-time PLT resolution.
Setting LD_BIND_NOW=1 avoided the crash and allowed NSH to start, which showed lazy binding was the trigger.

The 32-bit system clock has a limited range (~497 days) and the
configuration knob is no longer worth the complexity given that
practically every modern target already enables it. Make 64-bit
time_t/clock_t/sclock_t/nuttx_time_t the only supported flavor.
Specifically:
- Drop the SYSTEM_TIME64 Kconfig option and its dependent
PERF_OVERFLOW_CORRECTION/HRTIMER guards in sched/Kconfig.
- Remove every #ifdef CONFIG_SYSTEM_TIME64 branch in headers
(include/{sys/types.h,limits.h,inttypes.h,nuttx/clock.h,
nuttx/fs/hostfs.h}) and core code paths
(sched/clock/clock.h, drivers/power/pm/pm_procfs.c,
drivers/rpmsg/rpmsg_ping.c, fs/procfs/fs_procfsuptime.c,
libs/libc/wqueue/work_usrthread.c,
arch/avr/src/avrdx/avrdx_timerisr_tickless_alarm.c).
- Strip CONFIG_SYSTEM_TIME64=y from every board defconfig.
- Update Documentation/guides/rust.rst accordingly.

boards/sim/sim/sim/scripts/Make.defs adds `-no-pie` to ARCHCFLAGS /
ARCHPICFLAGS / LDFLAGS for every 64-bit non-Mac sim build. The
original comment ("To compile 64-bit Sim, adding no-pie is necessary
to prevent linking errors but this may cause other issues on
Ubuntu 20.") already flagged the workaround as fragile.
On HOST_ARM64 the option is in fact actively harmful. When gcc is
asked to produce a non-PIE executable on aarch64 it switches the
libgcc resolution path from the dynamic library
`libgcc_s.so.1` to the static archive `libgcc_s.a`. Ubuntu's
arm64 toolchain (and Debian / Raspbian arm64) **does not ship**
`libgcc_s.a` (only `libgcc_s.so.1`), so the link aborts with:
/usr/bin/ld: cannot find -lgcc_s
/usr/bin/ld: cannot find -lgcc_s (push-state / as-needed both fail)
collect2: error: ld returned 1 exit status
`ld --verbose` shows ld searching 20+ paths for `libgcc_s.a`,
finding only `libgcc_s.so` (a linker script pointing at
`libgcc_s.so.1`) which is invalid in non-PIE mode.
x86_64 Linux is unaffected because Ubuntu ships the static
`libgcc_s.a` (or a compatible static-fallback library) in its
amd64 libgcc-N-dev packaging. macOS, Windows and Cygwin go
through completely different code paths and never reach this
branch.
Extend the existing `else ifeq ($(CONFIG_HOST_MACOS),)` exclusion
to also cover HOST_ARM64 by concatenating the two variables in the
condition: `else ifeq ($(CONFIG_HOST_MACOS)$(CONFIG_HOST_ARM64),)`.
The condition is true only when both variables are empty (i.e. on
a 64-bit non-macOS non-aarch64 Linux host), so aarch64 hosts fall
through to gcc's default PIE-aware link path, which works
correctly. This concatenation idiom matches the style already
used elsewhere in the file (suggested by @xiaoxiang781216 in
review). The default text-segment placement
`-Ttext-segment=0x40000000` and `-Wl,--gc-sections` (set in the
common LDFLAGS just above this block) are honored regardless of
PIE / non-PIE.
Verified on NVIDIA Jetson Orin (Ubuntu 20.04 L4T, GCC 9.4) and
Raspberry Pi 4B (Debian 13 trixie, GCC 14.2):
$ ./build.sh sim:nsh -j$(nproc)
$ ./nuttx
NuttShell (NSH)
nsh> ostest
... [38 user_main stages, 14 PASS, 0 FAIL] ...
ostest_main: Exiting with status 0
x86_64 Linux behaviour is unchanged (the concatenation is empty
there, so the block is taken exactly as before).
Companion patch: arch/sim: rename nuttx libc memchr to avoid host
glibc collision (independent fix needed on the same aarch64 hosts).

BREAKING: In an effort to simplify NuttX initialization, NSH_ARCHINIT is
removed. board_app_initialize is also removed. BOARD_LATE_INITIALIZE now
performs all board initialization logic, and is by default enabled. All
references to these symbols are removed. BOARDIOC_INIT remains, but will
result in -ENOTTY when called. It is to be removed in a later commit.
Quick fix: Boards relying on NSH_ARCHINIT should now enable
CONFIG_BOARD_LATE_INITIALIZE instead. If the application needs
fine-grained control over board initialization from userspace, the logic
performed by BOARDIOC_INIT may be copied to the board_finalinitialize
function and used instead via BOARDIOC_FINALINIT. All
board_app_initialize logic provided by NuttX is now moved to
board_late_initialize, and the same should be done for out-of-tree
boards.

Migrate boards from static /etc/passwd files to build-time generation:
* Remove static etc/passwd files from SIM and ESP32-C3-legacy boards
* Update board configurations to enable BOARD_ETC_ROMFS_PASSWD_ENABLE
* Configure SIM board with login demo user (root/Administrator)
* Update board build rules to use newly generated passwd files
* Remove CMakeLists.txt dependency on static passwd in SIM
* Update MOTD string from username=admin to username=root
This completes the infrastructure migration for boards supporting
login functionality.
BREAKING CHANGE: The static etc/passwd files have been removed from
boards/sim/sim/sim/src/etc/passwd
boards/risc-v/esp32c3-legacy/esp32c3-legacy-devkit/src/etc/passwd
These boards now require CONFIG_BOARD_ETC_ROMFS_PASSWD_ENABLE=y and a
configured password. Any board carrying a custom static passwd file must
set RCRAWS to exclude etc/passwd and manage credentials via the new
Kconfig options or provide their own passwd generation. To fix: run
'make menuconfig' and navigate to:
Board Selection --->
Auto-generate /etc/passwd at build time --->
Admin password

This commit moves the canonical header to include/nuttx/debug.h,

and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
