That's promising, but it doesn't eliminate glibc as a potential problem.
Do we have glibc test suite results?

AFAIK I didn't include it. How would it get included?

It shouldn't be; it's not useful on most m68k platforms.

Here's the command I used:
debootstrap --arch=m68k --foreign --no-check-gpg --include=apt,nano unstable /export/debian-68k http://ftp.de.debian.org/debian-ports
Full disclosure:
# which debootstrap
/usr/sbin/debootstrap
# equery belongs /usr/sbin/debootstrap
* Searching for /usr/sbin/debootstrap ...
dev-util/debootstrap-1.0.87 (/usr/sbin/debootstrap)

Yep, it's Gentoo. But to be fair, it performed a native debootstrap just
fine. Next time I'll use the native chroot to debootstrap the m68k one.
