Fails to strip systemd on i386

[Lukas Märdian]

systemd FTBFS on i386, due to errors from debugedit during dh_strip.

The interesting part seems to be this:
debugedit: Failed to update file: invalid section entry size
dh_strip: error: debugedit --build-id --build-id-seed=systemd/249.5-2ubuntu1 debian/systemd/usr/lib/systemd/boot/efi/linuxia32.elf.stub returned exit code 1

Reproducer:
sbuild -djammy --arch=i386 --extra-package=../ninja-build_1.10.1-1+ppa1_i386.deb systemd_249.5-2ubuntu1.dsc

The extra-package was taken from https://launchpad.net/~slyon/+archive/ubuntu/testing/+build/22389874/+files/ninja-build_1.10.1-1+ppa1_i386.deb in order to mitigate a different issue, that seems to happen only locally and not on the Launchpad buildds:
dh_auto_build --builddirectory=build-deb
 cd build-deb && LC_ALL=C.UTF-8 ninja -j2 -v
ninja: error: rebuilding 'build.ninja': stat(/usr/bin/realpath): Value too large for defined data type
dh_auto_build: error: cd build-deb && LC_ALL=C.UTF-8 ninja -j2 -v returned exit code 1

I'm working around this issue by applying this to systemd's debian/rules:
