Andes toolchain will link crt0.o in default.

We can generate map file to see this feature.

If we don't need start files. We can use this setting.
Check "-nostartfiles".

Example:
nds32le-elf-gcc -Os -nostartfiles -static -T"../nds32.ld" -Wl,--gc-sections -o "demo-int.adx" ./src/crt0.o ./src/init-default.o ./src/init-soc.o ./src/interrupt.o ./src/main.o ./src/uart.o
This is the result. No crt0.o
