I will give it a look next week than i am back from UDS.
Launchpad-bugs tend to hide themself between Expires and random
machine-related segfaults, so at least for me they are quiet easy
to miss. Feel free to report them in the BTS, i personally tend to
monitor this way more closely, even if not ever bug gets an respond.

It complains? Really?
Without looking at the code it should just ignore these files and
that should be fine as it doesn't support stages anyway.

It's in cmdline/apt-get.cc method DoBuildDep(), but to read other files
we need to change the sources parser which should be in
apt-pkg/deb/debsrcrecords.cc debSrcRecordParser::BuildDepends
a new option defining the stage and we should be good to go.
So it shouldn't be that hard to do… (famous last words).

You are welcome. :)
Slightly related: If you have pointers to documentation on how someone
is supposed to be able to crossbuild, sharing would be nice.
As said, i haven't really touched crossbuilding so far…
