Argh. Checking upstream, it looks like the lazy_static crate does not
include this directory, so it's an artifact of the Debian package build.

It'd be trivial for dh-cargo to exclude the .pc directory, just as it
currently excludes the debian directory and .git directory. It's
theoretically possible that an upstream crate could include a .pc
directory; it *shouldn't*, but it could. Hopefully that doesn't happen.
