For this kind of thing, you should create your own config using the custom_scudo_config.h and defining SCUDO_USE_CUSTOM_CONFIG.

We are trying to move away from having these configs be arch specific. Also, not all riscv cpus will have the small address space that needs this change, which is why this should be in a custom config.
