Fix build on FreeBSD.

On FreeBSD, specifying an explicit dependency overrides any pattern
dependencies that might be applicable to a particular target.
The result is that no rules for pattern dependencies are considered.

A solution is to include all dependencies, including the pattern
dependencies, into the explicit dependency specification.
