Teach link_directories to recognize relative paths

We create CMake Policy CMP0015 to make link_directories() treat relative
paths with respect to the source tree while retaining compatibility.
This makes it consistent with include_directories() and other commands.

Changes based on patch from Alex.  See issue #9697.
