Comment 4 for bug 1898716

Not sure if this is the right place to report this, but these changes seem to cause automated mainline kernel builds to fail.

e.g.
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11.1/amd64/log
shows
make[3]: *** No rule to make target 'debian/canonical-certs.pem', needed by 'certs/x509_certificate_list'. Stop.

possibly because changes from this ticket were only partially migrated there e.g. in:

https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack/commit/?h=cod/mainline/v5.11.1&id=4508c61e1cf702e70308f1c1fbb0f26a45d0b853

which updated the configs, but not the rule for debian/canonical-certs.pem in debian/rules.
