SkiffOS: ${BUILDROOT_DIR}/host/bin/qemu-system is missing

Hello,

First, thanks for the great project!

I have a problem mentioned in the subject. It might be a silly mistake, but please help.

I ran the following steps, as mentioned here. by 2022.11.1 release. Host OS is Ubuntu 18.04.5 LTS.

$ export SKIFF_WORKSPACE=qemu
$ export SKIFF_CONFIG=intel/x64,virt/qemu
$ make configure
$ make compile
$ sudo apt install qemu-utils
$ make cmd/virt/qemu/run

The build itself look correctly completed as following.

Compilation complete!

However, I saw the following error.

/home/yokoyama/SkiffOS/configs/virt/qemu/scripts/execute_qemu.sh: line 70:
    /home/yokoyama/SkiffOS/workspaces/qemu/host/bin/qemu-system: No such file or directory

I don’t see qemu-system in workspaces/qemu/host/bin.

What step is required to build the qemu-system?

Any suggestion would be appreciated.

Regards,

Atsushi
