I guess the buildds would be running some kind of stock Debian
kernel from, probably, stable or oldstable. (The latter may be
problematic but I’ve seen it.) Or, at least, I hope they do.

Only on the porterbox amdahl; it exists and is 0.

The same would then be valid for porterboxen: for it to be a viable
armel porterbox, this must be set to 1.

Do you think it would be worth compiling a VERY tiny program from
execute_before_dh-auto-build that just runs an swp instruction, and
if that fails, issue a message pointing to your message? I’m doing
something similar for mksh wrt. the existence of /dev/{tty,pts,ptmx}
but here it can obviously only be done if not cross-compiling (but
that’s not a problem because the tests can only run then either).
