I have the same problem as you,and same error output.do you have fix?
For me, the following solution worked:
In biscuit/src/kernel/syscall.go:3314 change 512 to 1024 (or some number larger than 512). It seems that the new init executable generated is larger than 512 bytes, but the value is hardcoded in this line.
After this change, I ran make qemu CPUS=2 again and I was dropped in their shell
