There is one dependency in the src tree.

See PR 76362
    http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dbin/76362

The dependancy occurs when you have your source tree in a different
location than /usr/src, as the /sys directory is linked to
usr/src/sys.  If your source tree is in /usr/home/foo/src, and you set
/sys -> usr/home/foo/src/sys.  After a make installkernel the /sys
link now points to the wrong location.

Now when you build modules from ports, they'll either fail to find the
/sys directory or use the wrong /sys directory.

This affects users who may have moved their source trees and/or have
multiple source trees mounted from one NFS mount point (as given in
the example in the PR).
