ffmpeg | branch: master | Mans Rullgard <mans at mansr.com> | Tue Oct 23 03:28:08 2012 +0100| [a1f6ad69c77917a348650a745752535503a44f88] | committer: Mans Rullgard

fate: check that dependencies actually exist

This causes make to exit with an error message if a nonexistent
dependency is specified rather than silently dropping the test.
