Dear maintainer:

I tried to build this package in buster but it failed:

I don't know why it does not fail in the same way in reproducible builds,
but it is easy to see why it fails for me: The find command is finding
things inside the .pc directory used by quilt and friends. I would do
something like "find *" instead, if that's enough for the intended purpose.

Thanks.
