Hi Alexandre,

Please note that your email address bounces. I am therefore filing this
response as a Debian bug hoping to reach you this way. I strongly
recommend using a non-bouncing email provider for interacting with
Debian.

Thank you.

The typical way to cross build autoconf based packages is passing --host
to configure. Now your configure doesn't accept that option and your
override does not pass it. Still debhelper assumes that you have somehow
transferred that information to the build system (which you have not)
and therefore does not pass it in the dh_auto_build stage. We can force
that explicit passing by forcing the makefile buildsystem (instead of
the automatically selected autoconf buildsystem) and that makes
dh_auto_build pass CC and that makes things just work.

In my bounced mail, I asked you to not do any /usr-merge conversion for
systemd-cron.
