What we see here is that apt fails to install gcc-9-base:armhf, because
armhf is not a known architecture to dpkg. Since we're using the
chrootless mode, we're using the outer system's dpkg directly and that
happens to be an amd64 one. dpkg checks ./target/var/lib/dpkg/arch, but
that is not created due to the condition in mmdebstrap line 1005.
$options->{foreignarchs} turns out to be empty and thus creation is
skipped. This condition is wrong for the case at hand. The outcome
should be positive whenever the mode is chrootless and the native
architecture of the outer system doesn't match the architecture of the
chroot. Unconditionally creating /var/lib/dpkg/arch makes this
particular problem go away. We could craft a complex condition here, but
I think that it would be best to simply remove the condition, because
the presence of the arch file does not hurt. What do you think?
And yes, chrootless still quickly fails. One thing at a time.
