Works for me cross-building a system from x86_64-linux to armv7l-linux. Thank you.

Generally we apply patches unconditionally, to ensure they still apply (and keep applying).

Can you draft, retarget staging, and unconditionally apply there?

LGTM! I kicked off some more builds.

With this PR, systemd still builds on x86_64-linux native, and I can confirm aarch64-linux (cross, via x86_64-linux) also works.

I currently see a regression in staging for aarch64-linux native in gnutls, but this is unrelated to this PR:
