Now I am booting up the system in Qemu with

Now every command f.e. ls or ps works but gives a Illegal
Instruction in dmesg after exit(0).
[ 12.727280] Illegal Instruction in 'hush' (pid = 26, pc = 0x01d52e30)

Looks like that kernel is built without call0 userspace ABI support.
CONFIG_USER_ABI_CALL0_ONLY or CONFIG_USER_ABI_CALL0_PROBE
need to be set in the kernel config for correct signal delivery to
call0 processes.
