Select LIBC_ATOMIC_IRQ at the architecture level (ARM7TDMI, ARM926EJS, ARMv6M) for chips that do not support atomic operations natively. This covers all ARM7TDMI, ARM926EJS, and Cortex-M0 based chips automatically. Also select LIBC_ATOMIC_IRQ for specific non-ARM architectures (AVR, RISC-V, SPARC, Xtensa) that lack atomic instruction support. Signed-off-by: zhangyu117 <zhangyu117@xiaomi.com>
