This new dependency looks like it might have been unintentional.  rsync
is not documented in Documentation/process/changes.rst . And there must
be many other recursive file copying rules in the kernel build system,
which do *not* depend on rsync.

Maybe check with the kernel community first, verifying that this new
build dependency was in fact intended?  At the very least, that should
result in a patch to Documentation/process/changes.rst making this
explicit.
