Failed to run arch-test on arm64 machine

Prebuilt binary of Sail doesn't exist.
I was running test on Macbook M1, commit 164da62b64fa050569b22910ea207525884802ba.

I was running on an M2 without any errors (but having some dependency issue, i.e., riscof not found). Could you provide more details on how to reproduce this?

But I did nothing. I have even run make clean to ensure I didnt change anything in the codebase.
make arch-test is the only thing I ran

@vacantron, If including a darwin-arm64 (i.e., macOS ARM 64-bit binary) build of sail_cSim, what modifications would be necessary for rv32emu-prebuilt?
