[components][libc] run .init_array constructors in cplusplus_system_init

2026-10-11T08:11:07Z

Newer GCC emits C++ global constructors into .init_array, which many linker scripts keep outside [__ctors_start__, __ctors_end__), so they never ran. Walk __init_array_start/__init_array_end (weak) as well, skipping entries already covered by the ctors range. Add RT_USING_CPP_CRT_INIT for ports whose startup runtime already runs .init_array, default on for the simulator. With it set, only the .init_array walk is skipped; the ctors range is still walked. Renesas RA/RA_WIRELESS/RZ families select it when C++ is enabled: FSP SystemInit() already walks .init_array, so boards whose linker script only provides __init_array_* would run constructors twice. Boards that fold .init_array into the ctors range (ra6m3-hmi-board, ra8d1, rz) still run them once via RT-Thread. Also source env.sh and restore RTT_EXEC_PATH in ToolsCI project generate and dist steps so scons is on PATH (exit 127) and the ARM toolchain path is not overwritten by env.sh. Fixes #11778

[fix][libc] fix timegm month overflow calculation

2026-08-21T01:44:42Z

The original overflow logic used __spm[tm_mon] as the current month's length when normalizing tm_mday. This produced incorrect dates after crossing month boundaries and left zero or negative days unnormalized. Use the difference between adjacent cumulative day offsets with leap-year handling. Normalize overflow in tm_sec, tm_min, tm_hour, tm_mday, and tm_mon to keep the affected broken-down fields normalized. Add regression tests for month boundaries, leap years, large offsets, zero and negative days, negative time fields, combined overflow, and boundary carry cases.
