Thanks. I can reproduce this. The intention is to run the build
architecture 'generate_uudmap' binary, which is compiled earlier and
copied aside as build-generate_uudmap. Something goes wrong and the
build system ends up trying to run the host architecture binary instead,
which fails for obvious reasons.
I suspect upstream behaviour changes in the Configure -O (override)
argument handling but will need to dig into it some more.
In sake somebody wants to play with it, my steps in reproducing it in
a chroot (for armhf in this case) were roughly
# dpkg --add-architecture armhf
# apt update
# apt install crossbuild-essential-armhf
# apt -a armhf build-dep perl
$ dpkg-buildpackage -b -aarmhf
