The sandbox does not build on RISC-V when _init is not defined. Errors like the following were observed. Which function was referred to depended on the configuration.
/usr/bin/ld: common/built-in.o: in function `parse_stream_outer': /common/cli_hush.c:3175: undefined reference to `_init' collect2: error: ld returned 1 exit status make: *** [Makefile:1726: u-boot] Error 1
/usr/bin/ld: common/built-in.o: in function `bootdelay_process': common/autoboot.c:335: undefined reference to `_init' collect2: error: ld returned 1 exit status make: *** [Makefile:1726: u-boot] Error 1
