This didn't seem to be possible considering the entire point of Cython
is to generate C bindings, but some Python build systems remove the
build tree once the wheel has been generated, so we never get to see the
sources. As xargs will call the specified command even without any files
this results in sed failing.

Pass --no-run-if-empty so that this case doesn't result in an error.
