make -C./release ftp fails in src.txz due a symlink

[wosch]

Summary

ln -fs does not work as expected for the src.txz tarball. Split the command into two, always remove the sysmlink and create it again.

See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=288256

I think ports.txz has the same issue and should get the same fix. (Aside, please upload diffs with full context (e.g. with -U999999))

I cannot reproduce the error for ports.txz . But I agree that we should keep the targets in sync for better readability.

Fix possible symlink problem for ports.txz as well.
