As a workaround for this particular issue, you could do the following
without modifying svn at all:

    * Run svn through a wrapper script that saves the value of
      SSH_AUTH_SOCK to a file whose name is derived from the pid
      (e.g. echo $SSH_AUTH_SOCK >/tmp/ssh-auth-sock.$$).

    * In the hook script, walk up the chain of parent processes (e.g.
      by parsing the output from "ps") until it finds the pid of the
      wrapper script; then read the file that the wrapper script saved.

On the other hand, I think it would be reasonable to have a configurable
way of allowing specified environment variables to be passed to hook
scripts.
