Hello Felix,

I've just checked mc:qemuriscv64-sid-ports:isar-image-base target 
manually and
it fails with:

| E: Unable to locate package crossbuild-essential-riscv64

on do_rootfs_install task of sbuild-chroot-host recipe, which was 
predictable.
It was not failed on CI because of KFAIL on Sid-Ports targets (they are not
stable enough).

Overall preinstalling is good idea and will improve building speed, but we
should implement it in the right way.
